6) Connect only the recommended optional brake resistor between the + - PR.
These terminals must not be shorted.
7) Electromagnetic wave interference
The input/output (main circuit) of the inverter includes harmonic components, which
may interfere with the communication devices (such as AM radios) used near the
inverter. In this case, install the FR-BIF optional radio noise filter (for use in the input
side only) or FR-BSF01 or FR-BLF line noise filter to minimize interference.
8) Do not install a power capacitor, surge suppressor or radio noise filter (FR-BIF
option) in the output side of the inverter.
This will cause the inverter to trip or the capacitor and surge suppressor to be
damaged. If any of the above devices are installed, immediately remove them.
(When using the FR-BIF radio noise filter with a single-phase power supply, connect
it to the input side of the inverter after isolating the T phase securely.)
9) When rewiring after operation, make sure that the POWER lamp has gone off, and
when more than 10 minutes has elapsed after power-off, check with a meter etc.
that the voltage is zero. After that, start rewiring work. For some time after power-off,
there is a dangerous voltage in the capacitor.
Use the dedicated earth (ground) terminal to earth (ground) the inverter. (Do not 2
use the screw in the case, chassis, etc.) For the earth connection avoid direct
contact between aluminium and copper. Tin-plated cable lugs can be used if the
plating does not contain zinc. When tightening the screws take care not to
damage the thread in the aluminium frame.
The earth (ground) cable should be as thick as possible. Use the cable whose
gauge is equal to or larger than those indicated in the following table, and make
its length as short as possible. The earthing (grounding) point should be as near
as possible to the inverter to minimize the earth (ground) cable length.
(Unit: mm2)
To meet the Low Voltage Directive, use PVC insulated cables larger than specified
size in brackets ( ).

2) When using bar terminals and solid wires for wiring, their diameters should be
0.9mm maximum. If they are larger, the threads may be damaged during tightening.
3) Loosen the terminal screw and insert the cable into the terminal.
4) Tighten the screw to the specified torque.
Undertightening can cause cable disconnection or misoperation. Overtightening can
cause damage to the screw or unit, leading to short circuit or misoperation.
Tightening torque: 2.5kgcm
Note: When routing the stripped cables, twist them so that they do not become loose.
1) Use tweezers etc. to remove the connector in the source logic position and fit it in
the sink logic position.
Do this position changing before switching power on.
Note: 1. Make sure that the front cover has been installed securely.
2. The front cover has a capacity plate and the inverter a rating plate on it.
Since these plates have the same serial numbers, always reinstall the
removed cover to the inverter from where it was removed.
3. Always install the sink-source logic changing connector in either of the
positions. If two connectors are installed in these positions at the same time,
the inverter may be damaged.

Note: 1. The wiring distance between the inverter, brake unit and discharge resistor
should be within 2m. If twisted wires are used, the distance should be within

2. If the transistors in the brake unit should fail, the resistor will be extremely
hot, causing a fire. Therefore, install a magnetic contactor on the inverter's
power supply side to shut off current in case of failure.

INSTALLATION AND WIRING
1) Provide electrical and mechanical interlocks for MC1 and MC2 which are used for
commercial power supply-inverter switch-over.
When there is a commercial power supply-inverter switch-over circuit as shown
below, the inverter will be damaged by leakage current from the power supply due to
arcs generated at the time of switch-over or chattering caused by a sequence error.
2) If the machine must not be restarted when power is restored after a power failure,
provide a magnetic contactor in the inverter's primary circuit and also make up a
sequence which will not switch on the start signal.
If the start signal (start switch) remains on after a power failure, the inverter will
automatically restart as soon as the power is restored.
3) Since the input signals to the control circuit are on a low level, use two or more
parallel micro signal contacts or a twin contact for contact inputs to prevent a contact
fault.
4) Do not apply a large voltage to the contact input terminals (e.g. STF) of the control
circuit.
5) Do not apply a voltage directly to the alarm output signal terminals (A, B, C).
Always apply a voltage to these terminals via a relay coil, lamp, etc.
6) Make sure that the specifications and rating match the system requirements.

Note: A power factor improving capacitor and surge suppressor on the inverter's
output side may overheat or be damaged due to the harmonics of the inverter
output. Also, when an overcurrent flows in the inverter, the overcurrent
protection is activated. Hence, when the motor is driven by the inverter, do
not install a capacitor or surge suppressor on the inverter's output side. To
improve the power factor, insert a power factor improving reactor in the
inverter's input or DC circuit. For details, refer to the FR-A500/E500 series
technical information.

INSTALLATION AND WIRING
1) Basic measures
Do not run the power cables (I/O cables) and signal cables of the inverter in
parallel with each other and do not bundle them.
Use twisted shield cables for the detector connecting and control signal cables
and connect the sheathes of the shield cables to terminal SD.
Earth (Ground) the inverter, motor, etc. at one point.
2) Measures against noise which enters and causes misoperation of the inverter
When devices which generate noise (devices which use magnetic contactors,
magnetic brakes, many relays, for example) are installed near the inverter, the
inverter may misoperate due to noise. The following measures must be taken:
Provide surge suppressors for devices that generate noise to suppress noise.
Fit data line filters (Refer to page 36) to signal cables.
Ground the shields of the detector connection and control signal cables with cable
clamp metal.
33
INSTALLATION AND WIRING
3) Measures against noises which are radiated by the inverter causing misoperation of
peripheral devices.
Inverter-generated noises are largely classified into those radiated by the cables
connected to the inverter and inverter main circuit (I/O), those electromagnetically
and electrostatically inducted to the signal cables of the peripheral devices close to
the main circuit power supply, and those transmitted through the power supply
cables.

By decreasing the carrier frequency, the noise terminal voltage* can be reduced.
Use Pr. 72 to set the carrier frequency to a low value (1kHz).
Though motor noise increases at a low carrier frequency, selection of Soft-PWM
will make it unoffending.
By using shielded cables as signal cables, induction noise can be reduced greatly
(1/10 to 1/100). 2

If the carrier frequency setting is high, decrease the carrier frequency (Pr. 72) of

By using earth leakage circuit breakers durable against harmonics and surges
(e.g. Mitsubishi's Progressive Super Series) in the inverter's own line and other

Countermeasures
Use the electronic overcurrent protection of the inverter.
Decrease the carrier frequency. Note that motor noise increases. Selection of
Soft-PWM will make it unoffending.
To ensure that the motor is protected against line-to-line leakage currents, it is
recommended to use a temperature sensor to directly detect motor temperature.
Measures
It is recommended to take either of the following measures:

Note: 1. The earth leakage circuit breaker should be installed to the primary (power
supply) side of the inverter.
2. Ground fault in the secondary side of the inverter can be detected at the
running frequency of 120Hz or lower.
3. In the connection neutral point grounded system, the sensitivity current
becomes worse for ground fault in the inverter secondary side. Hence, the
protective grounding of the load equipment should be class D grounding (10
or less).
4. When the breaker is grounded on the secondary side of the inverter, it may be
unnecessarily operated by harmonics if the effective value is less than the
rating. In this case, note that the eddy current and hysteresis loss increase
and temperature rises.
* For the leakage current value of the noise filter installed on the inverter input
side, contact the corresponding filter manufacturer.

2) Compliance
We understand that the transistorized inverters themselves are not covered
directly by the EMC Directive. However, the EMC Directive applies to
machines/equipment into which transistorized inverters have been incorporated,
and these machines and equipment must carry the CE marks. Hence, we
prepared the technical information "EMC Installation Guidelines" (information
number BCN-A21041-202) so that machines and equipment incorporating
transistorized inverters may conform to the EMC Directive more easily.
43
INSTALLATION AND WIRING
2) Compliance
We have self-confirmed our inverters as products compliant to the Low Voltage
Directive and place the CE mark on the inverters.
3) Outline of instructions
* In the 400V class inverters, the rated input voltage range is three-phase, 380V
to 415V, 50Hz/60Hz.
* Connect the equipment to the earth (ground) securely. Do not use an earth
leakage circuit breaker as an electric shock protector without connecting the
equipment to the earth (ground).
* Wire the earth terminal independently. (Do not connect two or more cables to
one terminal.)
* The wire size on pages 18 and 19 are shown for following conditions.
Ambient Temp: 40C maximum
Wire installation: On wall without duct or conduits
If conditions are different from above, select appropriate wire according to
EN60204 ANNEX C TABLE 5.
* Use the no-fuse breaker and magnetic contactor which conform to the EN or
IEC Standard.
Design notice: Where residual-current-operated protective device (RCD) is
used for protection in case of direct or indirect contact, only
RCD of Type B is allowed on the supply side of this Electronic
2
Equipment (EE). Otherwise another protective measure shall
be applied such as separation of the EE from the environment
by double or reinforced insulation or isolation of EE and supply
system by a transformer. (Extract from EN51078)
* Use the inverter under the conditions of overvoltage category II and
contamination level 2 or higher specified in IEC664.
(a) To meet the overvoltage category II, insert an EN or IEC standard-
compliant earthed star connection isolation transformer in the input of the
inverter.
(b) To meet the contamination level 2, install the inverter in a control box
protected against ingress of water, oil, carbon, dust, etc. (IP54 or higher).
* On the input and output of the inverter, use cables of the type and size set
forth in EN60204 Appendix C.
* The operating capacity of the relay outputs (terminal symbols A, B, C) should
be 30VDC, 0.3A.
44
INSTALLATION AND WIRING
* The control circuit terminals shown with and on page 13 provide safe
separation to the main circuit terminal (primary circuit).

Safety
Perform test operation after making sure that safety is ensured if the machine
should become out of control.
Machine
Make sure that the machine is free of damage.
Parameters
Set the parameter values to match the operating machine (system) environment.
Test operation
Perform test operation and make sure that the machine operates safely under light
load at a low frequency. After that, start operation.
Since the Pr. 240 "Soft-PWM setting" value is factory-set to select Soft-PWM
control, the tone is different from that in the conventional non-low acoustic noise

Note: 1. Indicates the parameter of which setting is ignored when the general-
purpose magnetic flux vector control mode is selected.
2. Since calibration is made before shipment from the factory, the settings differ
slightly between inverters. The inverter is preset to provide a frequency
slightly higher than 50Hz.
3. When the control panel is used and the setting is 100Hz or more, the setting
increments are 0.1Hz.
4. The setting depends on the inverter capacity: (0.4K to 3.7K)/(5.5K to 7.5K).
5. Set to 85% of the rated inverter current for the 0.4K, 0.75K.
6. If "2" is set in Pr. 77 (parameter write inhibit selection), the setting cannot be
changed during operation.
7. The half-tone screened parameters allow their settings to be changed during
operation if "0" (factory setting) has been set in Pr. 77 (parameter write
inhibit selection). (However, the Pr. 72 value may be changed during PU
operation only.)

PARAMETERS
<Setting>
Use Pr. 1 to set the upper limit of the output frequency. If the frequency of the
frequency command entered is higher than the setting, the output frequency is
clamped at the maximum frequency.
To perform operation over 120Hz, set the upper limit of the output frequency in
Pr. 18.
(When the Pr. 18 value is set, Pr. 1 automatically changes to the frequency in
Pr. 18. Also, when the Pr. 1 value is set, Pr. 18 automatically changes to the
frequency in Pr. 1.)
Use Pr. 2 to set the lower limit of the output frequency.
CAUTION
When the Pr. 2 setting is higher than the Pr. 13 "starting frequency" value,
note that the motor will run at the set frequency by merely switching the
start signal on, without entering the command frequency.

Set the output current level at which the output frequency is adjusted to prevent the
inverter from coming to an alarm stop due to overcurrent etc.
For high-speed operation at or over the motor base frequency, acceleration may not
be made because the motor current does not increase.
To improve the operation characteristics of the motor in such a case, the stall
prevention level in the high-frequency range can be reduced. This is effective for
operation of a centrifugal separator up to the high-speed range. Normally, set 50Hz
in Pr. 66 and 100% in Pr. 23.
For operation in the high-frequency range, the current in the locked motor state is
smaller than the rated output current of the inverter and the inverter does not result
in an alarm (protective function is not activated) if the motor is at a stop. To improve
this and activate the alarm, the stall prevention level can be reduced.

Pr. 180 to Pr. 183 (input terminal function selection) to set signals RH, RM and RL.
Note: 1. The frequency can be varied by RH (acceleration) and RM (deceleration)
between 0 and the maximum frequency (Pr. 1 or Pr. 18 setting).
2. When the acceleration or deceleration signal switches on, the set frequency
varies according to the slope set in Pr. 44 or Pr. 45. The output frequency 4
acceleration/deceleration times are as set in Pr. 7 and Pr. 8, respectively.
Therefore, the longer preset times are used to vary the actual output frequency.
3. If the start signal (STF or STR) is off, turning on the acceleration (RH) or
deceleration (RM) signal varies the set frequency.
4. The frequency setting storage function stores in memory the remotely-set

PARAMETERS
Use Pr. 68 to set the waiting time from when an inverter alarm occurs until a restart
in the range 0.1 to 360 seconds.
Reading the Pr. 69 value provides the cumulative number of successful restart
times made by retry. The setting of "0" erases the cumulative number of times.
Note: 1. The cumulative number in Pr. 69 is incremented by "1" when retry operation
is regarded as successful, i.e. when normal operation is continued without
the protective function (major fault) activated during a period five times
longer than the time set in Pr. 68.
2. If the protective function (major fault) is activated consecutively within a
period five times longer than the above waiting time, the control panel may
show data different from the most recent data or the parameter unit
(FR-PU04) may show data different from the first retry data. The data stored
as the error reset for retry is only that of the protective function (major fault)
which was activated the first time.
3. When an inverter alarm is reset by the retry function at the retry time, the
stored data of the electronic over current protection, etc. are not cleared.
(Different from the power-on reset.)
CAUTION
When you have selected the retry function, stay away from the motor and
machine unless required. They will start suddenly (after the reset time
has elapsed) after occurrence of an alarm.

PARAMETERS
Note: 1. By entering the reset signal (RES) during operation, the inverter shuts off
output while it is reset, the data of the electronic overcurrent protection and
regenerative brake duty are reset, and the motor coasts.
2. The PU disconnection detection function judges that the PU is disconnected
when it is removed from the inverter for more than 1 second. If the PU had
been disconnected before power-on, it is not judged as an alarm.
3. To resume operation, reset the inverter after confirming that the PU is
connected securely.
4. The Pr. 75 value can be set any time. Also, if parameter (all) clear is
executed, this setting will not return to the initial value.
5. When the inverter is stopped by the PU stop function, PS is displayed but an
alarm is not output.
When the PU connector is used for RS-485 communication operation, the
reset selection and PU stop selection functions are valid but the PU
disconnection detection function is invalid.

Single-motor operation (one motor for one inverter) is performed.
The wiring length between the inverter and motor is within 30m. (If the length is over
30m, perform offline auto tuning with the cables wired.)

When you use the general-purpose magnetic flux vector control, you can perform the
offline auto tuning operation to calculate the motor constants automatically.
Offline auto tuning is made valid only when Pr. 80 is set to other than "9999" to
select the general-purpose magnetic flux vector control.
The general-purpose magnetic flux vector control can be used without using the
offline auto tuning function but if the motor used is not Mitsubishi's standard motor or
Mitsubishi's constant-torque motor (e.g. motor of another company make) or the
wiring distance is long, the motor can be run with the optimum operating
characteristics by using the offline auto tuning function.
Offline auto tuning
Automatically measures the motor constants used for general-purpose magnetic flux
vector control.
Offline auto tuning can be performed with the load connected. (As the load is
smaller, tuning accuracy is higher. Tuning accuracy does not change if inertia is
large.)
The offline auto tuning status can be monitored with the control panel
(FR-PA02-02) or PU (FR-PU04).
Offline auto tuning is available only when the motor is at a stop.
Tuning data (motor constants) can be copied to another inverter with the PU
(FR-PU04).
You can read, write and copy the motor constants tuned by the offline auto tuning.

PARAMETERS
<Operating conditions>
The motor is connected.
The motor capacity is equal to or one rank lower than the inverter capacity.
Special motors such as high-slip motors and high-speed motors cannot be tuned.
The motor may move slightly. Therefore, fix the motor securely with a mechanical
brake, or before tuning, make sure that there will be no problem in safety if the
motor runs.
*This instruction must be followed especially for vertical lift applications.
If the motor runs slightly, tuning performance is unaffected.
Offline auto tuning will not be performed properly if it is started when a reactor or
surge voltage suppression filter (FR-ASF-H) is connected between the inverter and
motor. Remove it before starting tuning.
<Setting>
Note: Pr. 83 and Pr. 84 are only displayed when the general-purpose magnetic flux
vector control is selected.
In these parameters, set the values given on the motor plate. Set 200V/60Hz

PARAMETERS
Note: 1. The R1 motor constant measured during in the offline auto tuning is stored
as a parameter and its data is held until the offline auto tuning is performed
again.
2. An instantaneous power failure occurring during tuning will result in a tuning
error.
After power is restored, the inverter goes into the ordinary operation mode.
Therefore, when STF (STR) is on, the motor runs in forward (reverse)
rotation.
3. Any alarm occurring during tuning is handled as in the ordinary mode. Note
that if an error retry has been set, retry is ignored.
4. The set frequency monitor displayed during the offline auto tuning is 0Hz.

When the offline auto tuning is used in vertical lift application, e.g. a lifter,
it may drop due to insufficient torque.

<Operating procedure>
1. Set "801" in Pr. 77. Only when the Pr. 80 setting is other than "9999", the
parameter value of the motor constant (Pr. 90) can be displayed. Though the
parameter values of other than the motor constant (Pr. 90) can also be displayed,
they are parameters for manufacturer setting and should be handled carefully
without misuse.

7) Error code
If any error is found in the data received by the inverter, its definition is sent back to
the computer together with the NAK code. (Refer to page 125.)
120
PARAMETERS
Note: 1. When the data from the computer has an error, the inverter will not accept
that data.
2. Any data communication, e.g. run command, monitoring, is started when the
computer gives a communication request. Without the computer's command,
the inverter does not return any data. For monitoring, therefore, design the
program to cause the computer to provide a data read request as required.
3. When accessing the parameter settings, data for link parameter expansion
setting differs between the parameters as indicated below:

CAUTION
When the inverter's permissible communication time interval is not set,
interlocks are provided to disable operation to prevent hazardous
conditions. Always set the communication check time interval before
starting operation.
Data communication is not started automatically but is made only once
when the computer provides a communication request. If communication
is disabled during operation due to signal cable breakage etc, the inverter
cannot be stopped. When the communication check time interval has
elapsed, the inverter will come to an alarm stop (E.PUE).
The inverter can be coasted to a stop by switching on its RES signal or
by switching power off.
4
If communication is broken due to signal cable breakage, computer fault
etc, the inverter does not detect such a fault. This should be fully noted.

When the inverter's output current falls to "0", torque will not be generated. This may
cause a gravity drop when the inverter is used in vertical lift application.
To prevent this, the output current "zero" signal can be output from the inverter to close
the mechanical brake when the output current has fallen to "zero".
If the output current remains lower than the Pr. 152 setting during inverter operation
for longer than the time set in Pr. 153, the zero current detection (Y13) signal is

CAUTION
The zero current detection level setting should not be too high, and the
zero current detection time setting should not be too long. Otherwise, the

CAUTION
Always perform test operation.
Stall prevention operation performed during acceleration may increase
the acceleration time.
Stall prevention operation performed during constant speed may cause

Terminal AM is factory-set to provide a 10VDC output in the full-scale state of each
monitored data. Pr. 901 allows the output voltage ratio (gain) to be adjusted
according to the meter reading. Note that the maximum output voltage is 10VDC.

5.1 Errors (Alarms)
If any fault has occurred in the inverter, the corresponding protective function is activated
to bring the inverter to an alarm stop and automatically give the corresponding error
(alarm) indication on the optional control panel or the parameter unit display.
If your fault does not correspond to any of the following errors or if you have any other
problem, please contact your sales representative.
Retention of alarm output signal ....When the magnetic contactor (MC) provided on
the power supply side of the inverter is opened at
the activation of the protective function, the
inverter's control power will be lost and the alarm
output will not be held.
Alarm indication .............................When the protective function is activated, the
operation panel display automatically switches to
the above indication.
Resetting method ...........................When the protective function is activated, the
inverter output is kept stopped. Unless reset,
therefore, the inverter cannot restart. Switch
power off once, then on again; or apply RES
signal for more than 0.1 seconds. Kept on, "Err."

Always run the inverter in a clean state.
When cleaning the inverter, gently wipe dirty areas with a soft cloth immersed in
neutral detergent or ethanol.
Note: Do not use solvent, such as acetone, benzene, toluene and alcohol, as they
will cause the inverter surface paint to peel off.
Do not use detergent or alcohol to clean the display and other sections of the
control panel as these sections do not like them.
