Warnings
CAUTION
Cables must not be connected or disconnected, nor signal tests carried out, while the power is
switched on.
The Varispeed F7 DC bus capacitor remains charged even after the power has been switched off. To
avoid an electric shock hazard, disconnect the frequency inverter from the mains before carrying out
maintenance. Then wait for at least 5 minutes after all LEDs have gone out.
Do not perform a withstand voltage test on any part of the inverter. It contains semiconductors, which
are not designed for such high voltages.
Do not remove the digital operator while the mains supply is switched on. The printed circuit board
must also not be touched while the inverter is connected to the power.
Never connect general LC/RC interference suppression filters, capacitors or overvoltage protection
devices to the inverter input or output.
To avoid unnecessary overcurrent faults, etc, being displayed, the signaling contacts of any contactor
or switch fitted between inverter and motor must be integrated into the inverter control logic (eg
baseblock).
The inverter must be operated with the appropriate line filters, following the installation instructions in
this manual and with all covers closed and terminals covered.
Only then will adequate protection be provided. Please do not connect or operate any equipment with
visible damage or missing parts. The operating company is responsible for any injuries or equipment
damage resulting from failure to heed the warnings in this manual.
IX
Safety Precautions and Instructions for Use
1. General
Please read these safety precautions and instructions for use thoroughly before installing and operating this
inverter. Also read all of the warning signs on the inverter and ensure they are never damaged or removed.
Live and hot inverter components may be accessible during operation. Removal of housing components, the
digital operator or terminal covers runs the risk of serious injuries or damage in the event of incorrect installa-
tion or operation. The fact that frequency inverters control rotating mechanical machine components can give
rise to other dangers.
The instructions in this manual must be followed. Installation, operation and maintenance may only be carried
out by qualified personnel. For the purposes of the safety precautions, qualified personnel are defined as indi-
viduals who are familiar with the installation, starting, operation and maintenance of frequency inverters and
have the proper qualifications for this work. Safe operation of these units is only possible if they are used
properly for their intended purpose.
The DC bus capacitors can remain live for about 5 minutes after the inverter is disconnected from the power.
It is therefore necessary to wait for this time before opening its covers. All of the main circuit terminals may
still carry dangerous voltages.
Children and other unauthorized persons must not be allowed access to these inverters.
Keep these Safety Precautions and Instructions for Use readily accessible and supply them to all persons with
any form of access to the inverters.
2. Intended Use
Frequency inverters are intended for installation in electrical systems or machinery.
Their installation in machinery and systems must conform to the following product standards of the Low Volt-
age Directive:
EN 50178, 1997-10, Equipping of Power Systems with Electronic Devices
EN 60204-1, 1997-12 Machine Safety and Equipping with Electrical Devices
Part 1: General Requirements (IEC 60204-1:1997)/
Please note: Includes Corrigendum of September 1998
EN 61010-1, A2, 1995 Safety Requirements for Information Technology Equipment
(IEC 950, 1991 + A1, 1992 + A2, 1993 + A3, 1995 + A4, 1996, modified)
CE marking is carried out to EN 50178, using the line filters specified in this manual and following the appro-
priate installation instructions.
4. Installation
Install and cool the inverters as specified in the documentation. The cooling air must flow in the specified
direction. The inverter may therefore only be operated in the specified position (eg upright). Maintain the
specified clearances. Protect the inverters against impermissible loads. Components must not be bent nor insu-
lation clearances changed. To avoid damage being caused by static electricity, do not touch any electronic
components or contacts.
X
5. Electrical Connection
Carry out any work on live equipment in compliance with the national safety and accident prevention regula-
tions. Carry out electrical installation in compliance with the relevant regulations. In particular, follow the
installation instructions ensuring electromagnetic compatibility (EMC), eg shielding, grounding, filter
arrangement and laying of cables. This also applies to equipment with the CE mark. It is the responsibility of
the manufacturer of the system or machine to ensure conformity with EMC limits.
Your supplier or OYMC representative must be contacted when using leakage current circuit braker in con-
junction with frequency inverters.
In certain systems it may be necessary to use additional monitoring and safety devices in compliance with the
relevant safety and accident prevention regulations. The frequency inverter hardware must not be modified.
6. Notes
The VARISPEED F7 frequency inverters are certified to CE, UL, and c-UL.
XI
EMC Compatibility
1. Introduction
This manual was compiled to help system manufacturers using YASKAWA frequency inverters to design and
install electrical switchgear. It also describes the measures necessary to comply with the EMC Directive. The
manual's installation and wiring instructions must therefore be followed.
Our products are tested by authorized bodies using the standards listed below.
Product standard: EN 61800-3:1996
EN 61800-3; A11:2000
3. Laying Cables
Measures Against Line-Borne Interference:
Line filter and frequency inverter must be mounted on the same metal plate. Mount the two components as
close to each other as possible, with cables kept as short as possible.
Use a power cable with well-grounded shield. Use a shielded motor cable not exceeding 20 meters in length.
Arrange all grounds so as to maximize the area of the end of the lead in contact with the ground terminal (eg
metal plate).
Shielded Cable:
– Use a cable with braided shield.
– Ground the maximum possible area of the shield. It is advisable to ground the shield by connecting the
cable to the ground plate with metal clips (see following figure).
XII
Ground clip Ground plate
The grounding surfaces must be highly conductive bare metal. Remove any coats of varnish and paint.
– Ground the cable shields at both ends.
– Ground the motor of the machine.

1. Do not remove or attach the Digital Operator or mount or remove the front cover using methods other
than those described above, otherwise the Inverter may break or malfunction due to imperfect contact.
2. Never attach the front cover to the Inverter with the Digital Operator attached to the front cover. Imperfect
contact can result.
IMPORTANT Always attach the front cover to the Inverter by itself first, and then attach the Digital Operator to the front
cover.
Inverters of 22 kW or More
For inverters with an output of 22 kW or more, remove the terminal cover and then use the following proce-
dures to remove the Digital Operator and main cover.

Installing a Moulded-case Circuit Breaker
When connecting the power input terminals (R/L1, S/L2, and T/L3) to the power supply using a moulded-case
circuit breaker (MCCB) observe that the circuit breaker is suitable for the Inverter.
• Choose an MCCB with a capacity of 1.5 to 2 times of the inverter's rated current.
• For the MCCB's time characteristics, be sure to consider the inverter's overload protection (one minute at
150% of the rated output current).
Installing an AC Reactor
If the Inverter is connected to a large-capacity power transformer (600 kW or more) or a phase advancing
capacitor is switched, an excessive peak current may flow through the input power circuit, causing the inverter
unit to break down.
To prevent this, install an optional AC Reactor on the input side of the Inverter or a DC reactor to the DC reac-
tor connection terminals.
This also improves the power factor on the power supply side.

Cable Length between Inverter and Motor
If the cable between the Inverter and the motor is long, the high-frequency leakage current will increase, caus-
ing the Inverter output current to increase as well. This may affect peripheral devices. To prevent this, adjust
the carrier frequency (set in C6-01, C6-02) as shown in Table 2.7. (For details, refer to Chapter 5 User
Parameters.)
Ground Wiring
Observe the following precautions when wiring the ground line.
• Always use the ground terminal of the 200 V Inverter with a ground resistance of less than 100 Ω and that
of the 400 V Inverter with a ground resistance of less than 10 Ω.
• Do not share the ground wire with other devices, such as welding machines or power tools.
• Always use a ground wire that complies with technical standards on electrical equipment and minimize the
length of the ground wire.
Leakage current flows through the Inverter. Therefore, if the distance between the ground electrode and
the ground terminal is too long, potential on the ground terminal of the Inverter will become unstable.
• When using more than one Inverter, be careful not to loop the ground wire.

3 (Enable stall prevention function with braking resistor)
The Braking Resistor Unit will not work properly if L3-04 is set to 1 (i.e., if stall prevention is enabled for
deceleration). Hence the deceleration time may be longer than the set time (C1-02/04/06/08).

Wiring Control Circuit Terminals
Wire Sizes
For remote operation using analog signals, keep the control line length between the Analog Operator or oper-
ation signals and the Inverter to 50 m or less, and separate the lines from main power lines or other control cir-
cuits to reduce induction from peripheral devices.
When setting frequencies from an external frequency source (and not from a Digital Operator), used shielded
twisted-pair wires and ground the shield for the largest area of contact between shield and ground.
The terminal numbers and the appropriate wire sizes are shown in Table 2.10.

Control Circuit Wiring Precautions
Observe the following precautions when wiring control circuits.
• Separate control circuit wiring from main circuit wiring (terminals R/L1, S/L2, T/L3, B1, B2, U/T1, V/T2,
W/T3, , 1, 2, and 3) and other high-power lines.
• Separate wiring for control circuit terminals MA, MB, MC, M1, M2, M3, M4, M5, and M6 (contact out-
puts) from wiring to other control circuit terminals.
• If using an optional external power supply, it shall be a UL Listed Class 2 power supply source.
• Use twisted-pair or shielded twisted-pair cables for control circuits to prevent operating faults.
• Ground the cable shields with the maximum contact area of the shield and ground.
• Cable shields have to be grounded on both cable ends.

Cable Lug Connector Sizes and Tightening Torque
The lug sizes and tightening torques for various wire sizes are shown in Table 2.19.
Precautions
The wiring method is the same as the one used for straight solderless terminals. Refer to page 2-35. Observe
the following precautions when wiring.
• Separate the control signal lines for the PG Speed Control Card from main power lines and other control
circuits.
• The shield must be connected to prevent operational errors caused by noise. Also, do not use any lines that
are more than 100 m long.
• Connect the shield (green grounding cable of the option card) to the shield terminal (E).
• Do not solder the ends of wires. Doing so may cause contact faults.
• When not using straight solderless terminals, strip the wires to a length of approximately 5.5 mm
• A separate power supply is required if the PG power supply consumption is higher than 200 mA. (If
momentary power loss must be handled, use a backup capacitor or other method.)
• Make sure not to exceed the PG cards maximum input frequency. The output frequency of the pulse gener-
ator can be calculated using the following formula.

Autotuning Mode
Autotuning automatically measures and sets the required motor data in order to achieve the maximum perfor-
mance. Always perform autotuning before starting operation when using the vector control modes.
When V/f control has been selected, only stationary autotuning for line-to-line resistance can be selected.
When the motor cannot be disconnected from the load, and Open Loop or Closed Loop Vector Control shall
be used perform stationary autotuning.
Example of Operation
Enter the motor rated output power (in kW), rated voltage, rated current, rated frequency, rated speed and
number of poles specified on the nameplate of the motor and then press the RUN key. The motor is automati-
cally run and the measured motor data are set in the E2- parameters.
Always set the above items. Otherwise autotuning cannot be started, e.g. it cannot be started from the motor
rated voltage input display.
A parameter can be changed from the setting displays using the Increment, Decrement, and Shift/RESET
keys. The parameter will be saved when the DATA/ENTER key is pressed. 3

Trial Operation
Overview of Settings
Make the required settings in quick programming mode and autotuning mode according to Fig 4.1.
Note With Open Loop or Closed Loop Vector control, the motor and Inverter must be connected 1:1. The motor capacity for which stable control is possible
is 50% to 100% of the Inverters capacity.
4-7
Open Loop Vector Control (A1-02 = 2)
Always perform autotuning. If the motor can be operated, perform rotating autotuning. If the motor cannot be
operated, perform non-rotating autotuning. Refer to the following section on Autotuning for details on auto-
tuning.
Autotuning
Autotuning sets motor parameters automatically when using Open Loop or Closed Loop Vector control, when
the cable length is long or the installation has changed.

Trial Operation
4-9
Precautions for Rotating and Non-rotating Autotuning
• If the motor rated voltage is higher than the power supply voltage, lower the base voltage value like shown
in Fig 4.3 to prevent saturation of the Inverter’s output voltage. Use the following procedure to perform
autotuning.
1. Input the voltage of the input power supply to T1-03 (Motor rated voltage).
2. Input the results of the following formula to T1-05 (Motor base frequency):
T1-03
T1-05 = Base frequency from motor nameplate × -----------------------------------------------
Motor rated voltage
3. Perform autotuning.
After the completing autotuning, set E1-04 (Max. output frequency) to the base frequency from the
motor’s nameplate.

• When speed precision is required at high speeds (i.e., 90% of the rated speed or higher), set T1-03 (Motor
rated voltage) to the input power supply voltage × 0.9. In this case at high speeds the output current will
increase as the input power supply voltage is reduced. Be sure to provide sufficient margin in the Inverter
current.

* 4.
For an inverter motor or vector control motor, the voltage and frequency may be lower than for a general-purpose motor. Always confirm setting on the
nameplate or in test reports. Also, if you know the no-load values, set the no-load voltage in T1-03 and the no-load frequency in T1-05 to obtain better
accuracy.
* 5. The setting range is valid if Heavy Duty is selected (C6-01=0, default setting). If Normal Duty 1 or 2 is selected (C6-01=1 or 2) the setting range will be
0.0 to 400.0 Hz.

Trial Operation
Application Settings
Parameters can be set as required in advanced programming mode (i.e. “ADV” is displayed on the LCD
screen). All the parameters which can be set in quick programming mode are also displayed and can be set in
the advanced programming mode.
Setting Examples
The following points are examples of settings for applications.
• When using an Inverter-mounted braking resistor (ERF), set L8-01 to 1 to enable ERF braking resistor
overheating protection.
• To prevent the machine from being operated in reverse, set b1-04 to 1 to disable reverse operation.
• To increase the speed of a 60 Hz motor by 10%, set E1-04 to 66.0 Hz.
• To use a 0 to 10 V analog signal for a 60 Hz motor for variable-speed operation between 0 and 54 Hz (0%
to 90% speed deduction), set H3-02 to 90.0%.
• To limit the speed range between 20% and 80% set d2-01 to 80.0% and set d2-02 to 20.0%.
No-load Operation
This section describes trial operation in which the motor is in no-load state, that means the machine is not con- 4
nected to the motor. To avoid failures caused by the the wiring of the control circuit it is recommended to use
the LOCAL mode. Press the LOCAL/REMOTE key on the Digital Operator to change to LOCAL mode (the
SEQ and REF indicators on the Digital Operator should be OFF).
Always confirm safety around the motor and machine before starting Inverter operation from the Digital
Operator. Confirm that the motor works normally and that no errors are displayed at the Inverter. For applica-
tions, at which the machine can be driven in one direction only, check the motor rotation direction.
Operation with Jog frequency reference (d1-17, default: 6.00 Hz) can be started and stopped by pressing and
releasing the JOG key on the Digital Operator. If the external control circuit prevents operation from the Dig-
ital Operator, confirm that emergency stop circuits and machine safety mechanisms are functioning, and then
start operation in REMOTE mode (i.e., with a signal from the control signal terminal). The safety precautions
must always be taken before starting the inverter and the motor connected.
Both, a RUN command (forward or reverse) and a frequency reference (or multi-step speed command) must
be provided to start Inverter operation.

Adjustment Suggestions
If hunting, vibration, or other problems originated in the control system occur during trial operation, adjust the
parameters listed in the following table according to the control method. This table lists the most commonly
used parameters only.
4-16
Adjustment Suggestions
• Do not change the Torque Compensation Gain (C4-01) from its default setting of 1.00 when using Open
Loop Vector control.
• If speeds are inaccurate during regeneration in Open Loop Vector control, enable Slip Compensation dur-
ing regeneration (C3-04 = 1).
• Use slip compensation to improve speed control during V/f control (A1-02 = 0).
Set the Motor Rated Current (E2-01), Motor Rated Slip (E2-02), and Motor No-load Current (E2-03), and
then adjust the Slip Compensation Gain (C3-01) to between 0.5 and 1.5. The default setting for V/f control
is C3-01 = 0.0 (slip compensation disabled).
• To improve speed response and stability in V/f control with a PG (A1-02 = 1), set the ASR parameters
(C5-01 to C5-05) to between 0.5 and 1.5 times the default value. (Normally it is not necessary to adjust this
setting.)

The following parameters will also affect the control system indirectly.

Torque Torque
Constant torque means a constant load torque for all motor speed. Typical Variable torque means that the load torque will increase as the speed
applications are pushers, conveyors, cranes, and other high friction or increases. Typical applications are fans and pumps. Normally not much
heavy loads. These applications may require overload capability. overload capability is required.

Application and Overload Selections
Setting Precautions
* 1. The rated current depends on on the Heavy/Normal Duty selection. (See page 9-2, Specifications by Model for details)
* 2. If the carrier frequency in Heavy Duty mode is set to a higher value than 2.5kHz, a current derating must be considered.
6
* 3. The factory setting and the maximum carrier frequecny depend on the inverter capacity. (See page 9-2, Specifications by Model for details)
• If speed and torque vary at low speeds: Lower the carrier frequency.
• If Inverter noise is affecting peripheral devices: Lower the carrier frequency.
• If leakage current from the Inverter is large: Lower the carrier frequency.
• If metallic noise from the motor is large: Increase the carrier frequency.
6-3
• When using V/f control or V/f control with PG, the carrier frequency can be set to vary depending on the

The frequency gain for terminal A1 is the product of H3-02 and gain which is input at terminal A2. For exam-
ple, when H3-02 is set to 100% and the terminal A2 input is 5 V, the frequency reference gain will be 50%.
Frequency reference
For example, if H3-02 is 100%, H3-03 is 0%, and the terminal A2 input is 1 V, the frequency reference when
0 V is input to A1 will be 10% of the maximum output frequency (E1-04).

Operation Avoiding Resonance (Jump Frequency Function)
The jump frequency function allows the prohibition or “jumping” of certain frequencies within the Inverter’s
output frequency range so that the machine can operate without oscillations caused by resonant frequencies of
the machine.
It can also be used for deadband control.
During acceleration and deceleration the output frequency goes linear through the prohibited frequency
ranges, i.e. no output frequency jumps are performes
During constant speed operation an operation within the jump frequency range is prohibited.

ASR Gain and Integral Time Adjustments for Closed Loop Vector Control
General Procedure
1.Operate the motor at zero speed.
2.Increase C5-01 (ASR proportional gain 1) to a level where no oscillation in the motor speed occurs.
3.Decrease C5-04 (ASR integral time 2) to a level where no oscillation in the motor speed occurs.
4.Increase the speed and observe the motor speed. If oscillations occur at any speed the gain must be
decreased and/or the integral time must be increased.
5.If the speed is stable at all speeds the adjustment is completed.
Fine Adjustments
When an even finer ASR adjustment is required, adjust the gain and integral time while observing the speed
waveform using the analog output terminals FM and AM. The necessary parameter settings are shown in the
following table.

Setting Precautions
• When the output torque reaches the torque limit, control and compensation of the motor speed is disabled
to prevent the output torque from exceeding the torque limit. The torque limit has the priority.
• When using the torque limit for hoist applications, do not carelessly lower the torque limit value, as this
may result in motor stalling.
• When using an analog input for torque limit setting, an analog input value of 10 V/20 mA is equal to a
torque limit of 100% of the motor rated torque. To raise the torque limit value at an analog input of 10
V/20 mA for instance to 150% of the rated torque, set the input terminal gain to 150.0 (%). Adjust the gain
for multi-function analog input terminal A2 using H3-10.
• The torque limit accuracy is ±5% at an output frequency of 10 Hz or above. When output frequency is
lower than 10 Hz, the accuracy is lowered.

NO/NC) in one of the parameter H2-01 to H2-03 (digital output terminals M1-M2, M3-M4, and M5-M6 func-
tion selection).
Overtorque/undertorque is detected by:
• observing the output current in V/f control with or without PG (the inverter rated output current is equal to
100%).
• observing the torque reference value in Open Loop and Closed Loop Vector control (the motor rated
torque is equal to 100%).

• When using a general-purpose motor (standard motor), the cooling ability will be lowered by f1/4 (fre-
quency). Consequently, a low output frequency may cause motor overload protection (OL1) to occur, even
when the output current is below the rated current. If the motor is operated at the rated current at a low fre-
quency, use a special motor which is externally cooled.

Limiting Motor Rotation Direction and Output Phase Rotation
If the motor reverse rotation is prohibited, a reverse run command will not be accepted, even if it is input. Use
this setting for applications in which reverse motor rotation can cause problems (e.g., fans, pumps, etc.)
In V/F mode it is also possible to change the output phase order by changing a parameter. This is much easier
and faster than changing the wiring if the motor rotational direction is wrong. If this function is used a prohi-
bition of reverse direction is not possible.

Setting Precautions
• When both external search commands 1 and 2 are set for the multi-function contact terminals, an OPE03
(invalid multi-function input selection) operation error will occur. Set either external search command 1 or
external search command 2.
• If speed search during startup is selected when using V/f control with PG or Closed Loop Vector control
the unit will start from the frequency detected by PG.
• If performing speed search using external search commands, design the control circuit so that the run com-
mand and external search command are both ON. These two commands must be kept on, at least for the
time set in parameter L2-03.
• If the Inverter output is equipped with a contactor, set the contactor operation delay time in the Speed
Search Wait Time (b3-05). The factory setting is 0.2 s. When not using a contactor, you can reduce the
search time to 0.0 s. After waiting for the speed search wait time, the Inverter starts the speed search.
• Parameter b3-02 (current detection level for search completion) is effective only when current detection
speed search is selected. When the current falls below the detection level, the speed search is supposed to
be as completed, and the motor accelerates or decelerates to the set frequency.
• If an overcurrent (OC) is detected when using speed search after power recovery, lengthen the Minimum
Baseblock Time (L2-03).

Restarting Operation After Transient Error (Auto Restart Function)
If an Inverter error occurs during operation, the Inverter will perform self-diagnosis. If no error is detected, the
Inverter will automatically restart. This is called the auto restart function.
Set the number of auto restarts in parameter L5-01.
The auto restart function can be applied to the following errors.
• OC (Overcurrent) • RH (Braking resistor overheated)
• GF (Ground fault) • RR (Braking transistor error)
• PUF (DC bus fuse blown) • OL1 (Motor overload)
• OV (Main circuit overvoltage) • OL2 (Inverter overload)
• UV1 (Main Circuit Undervoltage, Main Circuit MC Operation Failure)* • OH1 (Motor overheat)
If an error that is not listed above occurs, the protection function will operate and the auto restart function will
not work.

The most likely causes of RH (Mounted braking resistor overheating) faults are that the deceleration time is
too short or that the motor regeneration energy is too large. In these cases, lengthen the deceleration time or
replace the Braking Resistor with one with a higher braking capacity.

This function is not applicable for protecting external braking resistors. When external braking resistors are
used together with the internal braking chopper, L8-01 should be set to 0 to disable the internal braking
resistor protection.

Inverter Overheat Protection
The Inverter is protected against overheating using a thermistor that detects the heatsink temperature.
When the overheat temperature level is reached the inverter output is switched off.
To prevent a suddenly and unexpected stop of the inverter due to an overtemperature, an overheating
pre-alarm can be output. The temperature level for that pre-alarm can be set in parameter L8-02. Using
parameter L8-03 the inverter operation when an overtemperature occurs can be selected.
If a multifunction output is programmed for this function the output is switched ON when the heatsink temper-
ature exceeds the overheat pre-alarm level set in L8-02.

Raising and Lowering Frequency References Using Contact Signals
(UP/DOWN)
Using the UP and DOWN commands the frequency references can be raised or lowered by switching a pair of
digital inputs.
To use this function, set two of the parameters H1-01 to H1-05 (digital input terminal S3 to S7 function selec-
tion) to 10 (UP command) and 11 (DOWN command). Be sure to allocate two terminals so that the UP and
DOWN commands are used as a pair. Otherwise an OPE03 alarm will be displayed.
The table below shows the possible combinations of the UP and DOWN commands and the corresponding
operation.
Operation Acceleration Deceleration Hold Hold
Up command ON OFF ON OFF
The change of the output frequency depends on the acceleration and deceleration times. Be sure to set b1-02
(Run command selection) to 1 (Control circuit terminal).
Precautions
Setting Precautions
If multi-function input terminals S3 to S7 are set as follows, operation error OPE03 (Invalid multi-function
input selection) will occur:
• Only either the UP command or DOWN command has been set.
• UP/DOWN commands and Acceleration/Deceleration Ramp Hold have been allocated at the same time.
Application Precautions
• Frequency references which use the UP/DOWN commands are limited by the frequency reference upper
and lower limits set in parameters d2-01 to d2-03. In this case the value from the input A1 becomes the fre-
quency reference lower limit. If using a combination of the frequency reference from terminal A1 and the
frequency reference lower limit set in either parameter d2-02 or d2-03, the larger limit value will become
the frequency reference lower limit.
• If inputting the run command when using UP/DOWN commands, the output frequency accelerates to the
frequency reference lower limits set in d2-02.
• When using UP/DOWN commands, multi-step operations are disabled.
• When d4-01 (Frequency Reference Hold Function Selection) is set to 1, the frequency reference value
using the UP/DOWN functions is stored even after the power supply is turned OFF. When the power sup-
ply is turned ON and the run command is input, the motor accelerates to the frequency reference that has
been stored. To reset (i.e., to 0 Hz) the stored frequency reference, turn ON the UP or DOWN command
while the run command is ON.

time. Otherwise operation error OPE03 (invalid multi-function input selection) will occur.
• Acceleration/Deceleration Ramp Hold command
• UP/DOWN command
• Trim Control Increase/Decrease command
Application Precautions
• When performing sample/hold of analog frequency reference, be sure to close the digital input for 100 ms
or more. If the sample/hold time is less than 100 ms, the frequency reference will not be held.
• The frequency reference value that is held will be deleted when the power supply is turned OFF.

The checksum is calculated in the following way:
1. The starting value of the 16 Bit data-word, that is used for the calculation, has to be set to FFFFH.
2. An Exclusive OR operation has to be performed with the starting value and the slave address.
6
3. The result has to be shifted to the right until the overflow bit becomes 1.
4. When this bit becomes 1, an Esclusive OR operation with the result of step 3 and the fix value A001H has
to be performed.
5. After 8 shift operations (every time when the overflow bit becomes 1, an Exclusive OR like in step 4 has to
be done), perform an Exclusive OR operation with the result of the former operations and the next data
package (8 bit function code). Again the result of this operation has to be shifted 8 times and if needed it
has to be interconnected with the fix value A001H using an Exclusive OR operation.
6. The same steps have to be performed with the data, first with the higher byte and then with the lower byte
until all data are proceeded.
7. The result of these operations is the checksum. It consists of a high and a low byte.

The following example clarifies the calculation method. It shows the calculation of a CRC-16 code with the
slave address 02H (0000 0010) and the function code 03H (0000 0011). The resulting CRC-16 code is D1H
for the lower and 40H for the higher byte. The example calculation in this example is not done completely
(normally data would follow the function code).

Writing to Multiple Inverter Memory Registers
The writing of inverter memory registers works similar to the reading process, i.e. the address of the first reg-
ister that is to be written and the quantity of to be written registers must be set in the command message.
The to be written data must be consecutive, starting from the specified address in the command message. The
data order must be higher 8 bits, then lower 8 bits. The data must be in memory register address order.
The following table shows an example of a message where a forward operation has been set with a frequency
reference of 60.0 Hz for the inverter with the slave address 01H.

ENTER Command
When writing parameters to the Inverter from the PLC using MEMOBUS communications, the parameters are
6
temporarily stored in the parameter data area of the Inverter. To enable these parameters in the parameter data
area the ENTER command must be used.
There are two types of ENTER commands:
• ENTER commands that enable parameter data in RAM only (changes will be lost after power loss)
• ENTER commands that write data into the EEPROM (non-volatile memory) of the Inverter and enable the
data in RAM at the same time.
The following table shows the ENTER command data. ENTER command data can only be written.
The ENTER command is enabled by writing 0 to register number 0900H or 0910H.

0900H Write parameter data to EEPROM, RAM is refreshed
0910H Parameter data are not written to EEPROM, but refreshed in RAM only.
• The maximum number of times you can write to EEPROM is 100,000. Do not frequently exe-
cute ENTER commands (0900H) that write into EEPROM.
INFO • The ENTER command registers are write-only. Consequently, if these registers should be read
out, the register address will become invalid (Error code: 02H).
• An ENTER command is not required if reference or broadcast data are sent to the inverter.

Individual Functions
Self-Diagnosis
The Inverter has a built-in function for self-diagnosing the functioning of the serial communication interface
circuits. This function is called the self-diagnosis function. It uses the connected communications parts of the
send and receive terminals to receive data sent by the Inverter and thereby to check if communication is per-
formed normally.
To perform the self-diagnosis function use the following procedure.
1. Turn ON the inverter power supply, and set 67 (communications test mode) in parameter H1-05 (Terminal
S7 Function Selection).
2. Turn OFF the inverter power supply.
3. Perform the wiring according to Fig 6.74.
4. Turn ON the terminating resistance. (Turn ON pin 1 on DIP switch 1.)
5. Turn ON the inverter power supply.
During normal operation, the Digital Operator displays “PASS” on the display.
If an error occurs, a “CE” (MEMOBUS communications error) alarm will be displayed on the Digital Opera-
tor, the error contact output will be turned ON, and the Inverter operation ready signal will be turned OFF.
6-93
Using the Timer Function
The multi-function digital input terminals S3 to S7 can be used as timer function input terminals, and
multi-function output terminals M1-M2, M3-M4, and M5-M6 can be used as timer function output terminals.
By setting the delay time, you can prevent chattering of the sensors and switches.
• Set one of the parameters H1-01 to H1-05 (digital input terminal S3 to S7) to 18 (timer function input).
• Set H2-01 to H2-03 (multi-function output terminals M1-M2, M3-M4, and M5-M6 function selection) to
12 (timer function output).

Setting Precautions
• In PID control, the b5-04 parameter is used to prevent the calculated integral control value from exceeding
a specified amount. When the load varies rapidly, the Inverter response is delayed, and the machine might
get be damaged or the motor may stall. In this case, reduce the set value to speed up Inverter response.
• The b5-06 parameter is used to prevent the output value of the the PID control calculation from exceeding
a specified amount. The value is set taking the maximum output frequency as 100%.
• The b5-07 parameter is used to adjust PID control offset. The value is set in increments of 0.1%, taking the
maximum output frequency to be 100%.
• Set the filter time constant for the PID control output in b5-08. Enable this parameter to prevent machinery
resonance when machinery friction is high, or rigidity is poor. In this case, set the parameter to be higher
than the resonance frequency cycle duration. Increase this time constant to reduce Inverter responsiveness.
• Using b5-09, the PID output polarity can be inverted. If now the PID feedback value increases the output
frequency will be increased. This function is usable e.g. for vacuum pumps.
• Using b5-10, you can apply a gain to the PID control output. Enable this parameter to adjust the amount of
compensation if adding PID control output to the frequency reference as compensation (b5-01 = 3/4).
• When PID control output is negative, you can use parameter b5-11 to determine what happens to the
inverter output. When b1-04 (Prohibition of Reverse Operation) is set to 1 (enabled), however, the PID
output is limited to 0.
• Using the b5-17 parameter the PID target value can be raised or lowered with an accel./decel. ramp func-
tion (PID soft starter).
The normally used accel./decel. function (C1- parameters) is allocated after PID control so that,
depending on the settings, resonance with the PID control and hunting in the machinery may occur. Using
b5-17 this behaviour can be prevented.
The PID soft starter function can also be disabled or enabled using a multifunction digital input (H1-
has to be set to 34).

PID Sleep
The PID sleep function stops the Inverter when the PID output value falls below the sleep operation level
(b5-15) for the sleep operation time set in parameter b5-16. The inverter operation will resume, if the PID out-
put value exceeds the sleep operation level for the time set in parameter b5-16 or longer.
The PID sleep function works as well when the PID control is disabled. In this case the frequency reference
value is observed by the sleep function instead of the PID output value.
The PID sleep time chart is shown below.
So linear connection between the PID target value and the feedback can be realized.

Open Loop and Closed Loop Vector Control
In Open Loop and Closed Loop Vector control, the slip frequency is controlled so that motor efficiency is
maximized.
• Taking the motor rated slip for the base frequency as optimum slip, the inverter calculates the slip for the
optimal motor efficiency depending on the output frequency.
• Before using energy saving always perform autotuning.
• If hunting occurs reduce the set value in b8-02 (Energy-saving Gain), or increase the set value in b8-03
(Energy-saving Filter Time Constant).
Field Weakening
The field weakening function is used to lower the output voltage when the motor load changes to a low level
(no load). Thereby energy can be saved and motor audible noise is reduced.
Note that this function is designed for the usage with one low load condition that does not change. If the low
load condition changes, the field weakening function can not be optimized. In this case the energy saving
function should be preferred.
The function can be activated using a multifunction input. Therefore set one of the parameters H1-01 to H1-05
to 63.
Field weakening can be used in the V/f control modes only.

If E1-03 is set to F the V/f pattern can be set individually using the parameters E1-04 to E1-10. See Fig 6.81
for details.
Output voltage (V)
Frequency (Hz)
• If E1-03 is set to anything other than F, you can only read parameters E1-04 to E1-10.
• To set the V/f characteristics linear, set E1-07 and E1-09 to the same value. In this case, E1-08 will be
INFO ignored.
Setting Precautions
When the setting is to user-defined V/f pattern, beware of the following points:
• When changing control method, parameters E1-07 to E1-10 will change to the factory settings for that
control method.
• Be sure to set the four frequencies as follows:
E1-04 (FMAX) ≥ E1-06 (FA) > E1-07 (FB) ≥ E1-09 (FMIN)

Torque Control Operation
In torque control a torque value can be given as reference for the motor output. If the torque command and the
load are not balanced, the motor accelerates or decelerates.
The speed limit circuit prevents the motor speed from rising above certain value set by an anlaog input or
parameter d5-04. The speed limit function mainly consists of two parts, the priority circuit and the speed
limiter circuit.
The priority circuit selects between the torque reference value from the analog input or from the speed control-
ler (ASR) output. If the output speed is below the speed limit, the analog input value is taken as torque refer-
ence. Otherwise the ASR output value is taken as torque reference.
The speed limit circuit adds a speed supressing torque to the torque output if the speed exceeds the speed limit.
Together with the priority circuit it prevents the output speed from exceeding the speed limit.
The torque control block diagram is shown in Fig 6.82.

Individual Functions
The direction of the torque output from the motor will be determined by the sign of the analog signal input or
a digital input command. It does not depend on the direction of the run command. The direction of torque will
be as follows:
• Positive analog reference: Torque reference for forward motor rotation (counterclockwise as viewed from
the motor output axis).
• Negative analog reference: Torque reference for reverse motor rotation (clockwise as viewed from the
motor output axis).
The direction in which speed is controlled is determined by the sign of the speed limit signal and the direction
of the run command.
6
• Positive voltage applied: The speed in the forward direction will be limited for forward operation.
• Negative voltage applied: The speed in the reverse direction will be limited for reverse operation.
If the direction of the motor rotation and the speed limit direction are not the same, the speed will be limited
to 0.
6-119
Speed Limit Bias Setting
The speed limit bias can be set to limit both the forward and reverse speed to the same value. This differs from
the operation of the speed limit setting. To use the speed limit bias, set d5-04 to 0 and set the bias in d5-05 as
a percentage of the maximum output frequency.
To set 50% forward and reverse speed limits, set the speed limit setting to 0 (d5-03 = 2, d5-04 = 0, and d5-05
= 50). The range of torque control will be from -50% to 50% of the maximum output speed.
When using both, the speed limit and the speed limit bias, the speed range of torque control will be the posi-
tive and negative speed limits with the speed limit bias added to each.
Example
The speed range of torque control when the forward speed limit is 50% and the speed limit bias is 10% is
shown in Fig 6.83. This figure does not take the priority circuit into account.
Positive torque
Reverse Forward
operation operation
Negative torque
Winding Operation
In a winding operation, the line (speed) and torque generated by the motor are in the same direction. For the
winding operation, both the speed limit and the torque reference input are positive. The motor will accelerate
when the torque reference input is larger than the load and will decelerate when it is smaller than the load. If
the motor turns faster than the speed limit, a negative compensation value is output from the speed limiter cir-
cuit. When the speed then drops below the speed limit, a positive compensation value is output. The torque
compensation is proportional to the ASR proportional gain. When the sum of the torque reference and the
torque compensation output by the speed limiter is the same as the actual load, the motor will stop accelerating
and run at a constant speed.
Rewinding Operation
In a rewinding operation, the line (speed) and torque generated by the motor are in the opposite directions. (In
this example, it is assumed that the line speed is positive and the torque reference input is negative.) For the
rewinding operation, the speed limit is positive and the torque reference input is negative. If the motor turns
faster than the speed limit, a negative compensation value is output from the speed limiter circuit. If the motor
is rotating in reverse, a positive compensation value is output. If the speed is 0 or is below the speed limit, a 0
compensation value is output. In this way, the output from the speed limiter is used to maintain the motor
speed between 0 and the speed limit. When the sum of the torque reference and the torque compensation out-

put by the speed limiter is the same as the actual load, the motor will stop accelerating and run at a constant
speed.

Speed/Torque Control Switching Function
It is possible to switch between speed control and torque control using one of the digital inputs (H1- = 71,
Speed/Torque Control Change). Speed control is performed when the input is OFF and torque control is per-
formed when the input is ON. The parameter d5-01 has to be set to 0.

Zero-Servo Function
The Zero-Servo function holds the motor when the motor is stopped in a so called Zero-Servo status. This
means, that if the frequency reference falls below the Zero-Speed level (parameter b2-01) a position loop is
activated and the motor is kept at the position, even if a load is applied.
The zero-servo function must be enabled using a digital input, which is programmed for is set to Zero-Servo
command (H1- = 72).
The actual deviation of the rotor position from the zero position can be monitored using parameter U1-35. The
shown value must be devided by to the get the displacement in encoder pulses.

Application Precautions
• Be sure to leave the run command input activated. If the run command is turned OFF, the output will be
interrupted and the zero-servo function will become inactive.
• The holding force of the Zero-Servo position loop can be adjusted in parameter b9-01. The holding force
will increase if the set value is increased. Oscillation and hunting may occur, if the setting is too large.
Adjust b9-01 after adjusting the speed controller (ASR).

• The Zero-Servo detection width is set as the allowable displacement from the Zero-Servo start position.
Set the b9-02 taking the number of displacement pulses from the PG multiplied by 4.
• The Zero-Servo completition signal will be turned OFF when the zero servo command is turned OFF.
Do not use the Zero-Servo for extended periods of time with 100% of torque. Inverter errors may result.
If the Zero Servo function shall be used continuously, make sure that the output current during the servolock
is 50% of the motor current or less.

Kinetic Energy Buffering
The kinetic energy buffering function can be used to decelerate to stop after a sudden power loss using the
kinetic energy of the rotating machine to maintain the DC bus voltage. Thereby an uncontrolled coasting of a
machine can be prevented. The function can be activated using a multifunction input that i.e. can be operated
by a DC bus undervoltage alarm output or by a voltage drop relay. A wiring example is shown in Fig. 6.80.

Generally, the A-phase leads when the rotation direction is counter-clockwise (CCW) seen from the shaft side
(FWD command is input).
Setting Number of Gear Teeth Between PG and Motor (F1-12 and F1-13)
If there are gears between the motor and PG, the gear ratio can be set using F1-12 and F1-13.
When the number of gear teeth has been set, the number of motor rotations within the Inverter is calculated
using the following formula.
No. of motor rotations (r/min.) = No. of input pulses from PG × 60 / F1-01 × F1-13 (No. of gear teeth on PG
side) / F1-12 (No. of gear teeth on motor side)
If F1-07 is set to 1, overshoot or undershoot may occur easily immediately after acceleration and decelera-
tion. To minimize the possibility of overshoot or undershoot occurring, set F1-07 to 0.
IMPORTANT
6-138
Option Cards
The dividing ratio can be set within the following range: 1/32 ≤ F1-06 ≤ 1. For example, if the dividing ratio is
1/2 (set value 2), half of the number of pulses from the PG are output at the pulse monitor.
Detecting Speed Difference between the Motor and Speed Reference (F1-04, F1-10
and F1-11)
Speed deviation is detected when the speed deviation (i.e., the difference between the speed reference and the
actual motor speed) is too large. Speed deviation (DEV) is detected only after a speed agreement (speed refer-
6
ence and actual motor speed are within the setting range of L4-02) and if a speed deviation higher than the set
value in F1-10 continues for longer than the time set in F1-11. After a speed deviation is detected, the Inverter
stops according to the setting in F1-04.
6-139
Analog Reference Cards
When using a AI-14B or A1-14U analog reference card, set parameter b1-01 (Reference selection) to 3
(Option Card).
The AI-14B provides 3 bi-polar input channels with 14-bit (plus sign) A/D conversion.
If b1-01 is set to 1 and F2-01 is set to 0, the channel 1 and 2 replace the analog inputs A1 and A2. A1 becomes
the frequency reference input and the function of A2 can be selected using parameter H3-09. In this case no
digital iput can be set for the Option/Inverter selection function (H1- = 2).
If b1-02 is set to 3 and F2-01 is set to 1, the sum of three input channels becomes the frequency reference
value.
The AI-14U provides 2 unipolar inputs channels with 14-bit A/D conversion. Channel 1 is a voltage input and
channel 2 is a current input. The sum of the channels 1 and 2 is the frequency reference. F2-01 does not need
to be set for the AI-14U option card.

Troubleshooting

Protective and Diagnostic Functions
This section describes the fault and alarm functions of the Inverter. These functions include fault detec-
tion, alarm detection, operatot programming error detection and auto-tuning error detection.
Fault Detection
When the Inverter detects a fault, the fault contact output operates and the Inverter output is switched OFF
causing the motor to coast to stop. (The stopping method can be selected for some faults.) A fault code is dis-
played on the Digital Operator.
When a fault has occurred refer to the following table to identify the fault and to correct the causes.
Use one of the following methods to reset the fault before restarting the Inverter:

expected when the system is started. If that occurs, use this section as a reference and perform the appro-
priate countermeasures.

The following causes are possible:
7-19
The motor stops during acceleration or when a load is connected.
The load may be too large. The motor’s responsiveness limit may be exceeded if it is accelerated too rapidly
by the Inverter’s stall prevention function or automatic torque boost function. Increase the acceleration time
(C1-01) or reduce the motor load. Also, consider increasing the motor size.
7-20
Troubleshooting
If There is Low Speed Control Accuracy Above Base Speed in Open Loop
Vector Control Mode
The Inverter’s maximum output voltage is determined by its input voltage. (For example, if 400 VAC is input,
then the maximum output voltage will be 400 VAC). Vector control uses voltage to control the currents within
the motor. If the vector control voltage reference value exceeds the Inverter output voltage capability, the
speed control accuracy will decrease because the motor currents cannot be properly controlled. Use a motor
with a low rated voltage compared to the input voltage, or change to Closed Loop Vector control.
7-21
If the Motor Overheats
The following causes are possible:
7-22
Troubleshooting
There may be resonance between the mechanical system's natural frequency and the carrier
frequency.
This is characterized by the motor running with no noise generation, but the machinery vibrates with a high-
pitched whine. To prevent this type of resonance, adjust the carrier frequency with parameters C6-02 to
C6-05.
There may be resonance between a mechanical system’s natural frequency and the output fre-
quency of the Inverter.
To prevent this resonance frequency use the Jump Frequency Function in parameters d3-, or have the
driven motor and load balanced to reduce vibration.
7-23
If auto-tuning has not been performed, proper performance may not be achieved for Closed Loop Vector Con-
trol. Perform auto-tuning or set the motor parameters through hand calculations. Alternatively, change the
Control Mode Selection to V/f Control (A1-02 = 0 or 1).

Maintenance and Inspection
Periodic Inspection
Check the following items during periodic maintenance.
• The motor should not vibrate or make unusal noises.
• There should be no abnormal heat generation from the Inverter or motor.
• The ambient temperature should be within the Inverter’s specifications.
• The ouput current value shown in U1-30 should not be higher than the motor or the Inverter rated current
for extended period of time.
• The cooling fan in the Inverter should be operating normally.
Before attempting any maintenance checks, make sure that the three-phase power is disconnected. With power
removed from the unit, the DC bus capacitors will stay charged for several minutes. The Charge LED in the
Inverter will glow red until the DC bus voltage is below 10VDC. To ensure that the DC bus is completely dis-
charged, measure between the positive and negative bus with a DC voltmeter set to the highest scale. Be sure
not to touch terminals immediately after the power has been turned off. Doing so can result in electric shock.

Inverter Application Precautions
Selection
Observe the following precautions when selecting an Inverter.
Installing Reactors
A large peak current will flow in the power input circuit when the Inverter is connected to a large-capacity
power transformer (600 kVA or higher) or when switching a compensating capacitor. Excessive peak current
can destroy the converter section. To prevent this, install a DC or AC reactor to improve the power supply
power factor.
DC reactors are built into Inverters of 22kW and more.
If a thyristor convertor, such as a DC drive, is connected in the same power supply system, connect a DC or
AC reactor regardless of the power supply conditions shown in the following diagram.
DC or AC reactor

Fig 10.1
Initial Torque
The startup and acceleration characteristics of the motor are restricted by the overload current ratings of the
Inverter that is driving the motor. The torque characteristic generally is different from those when starting a
motor on the power supply directly. If a large initial torque is required, select an Inverter one size bigger or
increase the capacity of both, the motor and the Inverter.

Inverter Application Precautions
Installation
Observe the following precautions when installing an Inverter.
Installation in Enclosures
Install the Inverter in a clean location where it is not subjected to oil mist, dust, and other contaminants, or
install the Inverter in a completely enclosed panel. Provide cooling measures and sufficient panel space so that
the temperature surrounding the Inverter does not exceed the allowable temperature. Do not install the Inverter
on wood or other combustible materials.
Installation Direction
Mount the Inverter vertically to a wall or other vertical surface.

Observe the following precautions when making settings for an Inverter.
Upper Limits
The maximum output frequency can be set up to 400Hz. Setting the output frequency too high can damage the
machine. So pay attention to the mechanical system and observe required limits for the output frequency.
Acceleration/Deceleration Times
The motor's acceleration and deceleration times are determined by the torque generated by the motor, the load
torque, and the load's inertial moment (GD2/4). If the stall prevention functions are activated during accelera-
tion or deceleration, it might be necessary to increase the acceleration or deceleration time.
To reduce the acceleration or deceleration times, increase the capacity of the motor and Inverter.

Handling
Observe the following precautions when wiring or performing maintenance for an Inverter.
Wiring Check
The Inverter will be internally damaged if the power supply voltage is applied to output terminal U, V, or W.
Check wiring for any mistakes before supplying power. Check all wiring and control sequences carefully.

Motor Application Precautions
High-speed Operation
When using the motor at a speed higher than the motor rated frequency (usually 50 Hz), problems may arise in
dynamic balance and bearing durability.
Noise
The noise generated in the motor depends on the carrier frequency. The higher the setting the less the gener-
ated noise is.

Using the Inverter for Special Motors
Observe the following precautions when using a special motor.
Pole-changing Motor
The rated input current of pole-changing motors differs from that of standard motors. Select an appropriate
Inverter according to the maximum current of the motor.
Submersible Motor
The rated input current of submersible motors is higher than that of standard motors. Therefore, always select
an appropriate Inverter according to the maximum current of the motor.
Explosion-proof Motor
When an explosion-proof motor is used, it must be subjected to an explosion-proof test in conjunction with the
Inverter. This is also applicable when an existing explosion-proof motor is to be operated with the Inverter.
Since the Inverter itself is, however, not explosion-proof, always install it in a safe place.
Gearmotor
The speed range for continuous operation differs according to the lubrication method and motor manufacturer.
In particular, continuous operation of an oil-lubricated motor in the low speed range may result in damaging.
If the motor is to be operated at a speed higher than 50 Hz, consult the manufacturer.
Synchronous Motor
A synchronous motor is not suitable for Inverter control.
Single-phase Motor
Do not use an Inverter for a single-phase capcitor motor. Any capacitors directly connected to the inverter out-
put may damage the Inverter.
