2.2 Wiring
Open the front cover, remove the cable guides and control terminal cover, and then
install the ground connection as specified. Complete the cable connections by
connecting an appropriately rated cable to the terminals on the power and control
terminal blocks. Read the following information carefully before carrying out wiring
connections to the inverter. All warning instructions must be followed.
15
Installing the Inverter
For the power terminal and control terminal wiring, the front cover must be
disassembled in order. Note that the disassembling procedure of front cover and
control terminal cover may vary depending on the product group. Disassemble each
cover in the following order:
1 Loosen the bolt that secures the front cover (R). Push and hold the latch on the
right side of the cover. Then remove the cover by lifting it from the bottom and
moving it away from the front of the inverter.
Note
If you have installed the remote keypad, remove the plastic cover under the lower-right
part of the control terminal cover, and then connect the remote keypad signal to the RJ-45
connector.
16
Installing the Inverter
Remove the front cover(s) and the control terminal cover. Then follow the instructions
below to install the ground connection for the inverter.
1 Locate the ground terminal and connect an appropriately rated ground cable to
the terminals. Refer to 1.5 Cable Selection on page 9 to find the appropriate
cable specification for your installation.
2 Connect the other ends of the ground cables to the supply earth (ground) terminal.
Note
• 200 V products require Class 3 grounding. Resistance to ground must be < 100Ω.
• 400 V products require Special Class 3 grounding. Resistance to ground must be less
than < 10 Ω.
Make sure to install ground connection between the equipment and the motor for safe
use. Otherwise it may cause an electrical shock and result in personal injury or even
death.
17
Installing the Inverter
The following illustration shows the terminal layout on the power terminal block. Refer
to the detailed descriptions to understand the function and location of each terminal
before making wiring connections. Ensure that the cables selected meet or exceed
the specifications in 1.5 Cable Selection on page 9 before installing them.
• Apply rated torques to the terminal screws. Loose screws may cause short circuits
and malfunctions. Tightening the screw too much may damage the terminals and
cause short circuits and malfunctions.
• Use copper wires only with 600 V, 75℃ rating for the power terminal wiring, and 300
V, 75℃rating for the control terminal wiring.
• Do not connect two wires to one terminal when wiring the power.
• Power supply wirings must be connected to the R, S, and T terminals. Connecting
them to the U, V, W terminals causes internal damages to the inverter. Motor should
be connected to the U, V, and W Terminals. Arrangement of the phase sequence is
not necessary.

Installing the Inverter
5.5–7.5 kW
Note
• Do not use 3 core cables to connect a remotely located motor with the inverter.
• When operating Brake resistor, the motor may vibrate under the Flux braking
operation. In this case, please turn off the Flux braking (Pr.50).
• Make sure that the total cable length does not exceed 665 ft (202 m). For inverters < =
4.0 kW capacity, ensure that the total cable length does not exceed 165 ft (50 m).
• Long cable runs can cause reduced motor torque in low frequency applications due to
voltage drop. Long cable runs also increase a circuit’s susceptibility to stray
capacitance and may trigger over-current protection devices or result in malfunction of
equipment connected to the inverter. Voltage drop is calculated by using the following
formula:
Voltage Drop (V) = [√3 X cable resistance (mΩ/m) X cable length (m) X current (A)] /
1000
• Use cables with the largest possible cross-sectional area to ensure that voltage drop is
minimized over long cable runs. Lowering the carrier frequency and installing a micro
surge filter may also help to reduce voltage drop.
Distance < 330 ft (50 m) < 330 ft (100 m) > 330 ft (100 m)
Allowed Carrier Frequency < 15 kHz < 5 kHz < 2.5 kHz
20
Installing the Inverter
Do not connect power to the inverter until installation has been fully completed and the
inverter is ready to be operated. Otherwise it may cause an electrical shock and result in
personal injury or even death.
• Power supply cables must be connected to the R, S, and T terminals and output wiring
to the motor must be connected to the U, V, and W terminals. Opposite connections
may damage the product.
• Use insulated ring lugs when connecting cables to R/S/T and U/V/W terminals.
• The inverter’s power terminal connections can cause harmonics that may interfere with
other communication devices located near to the inverter. To reduce interference the
installation of noise filters or line filters may be required.
• Are advanced-phase capacitors, surge protection and electromagnetic interference
filters installed correctly?
• To avoid circuit interruption or damaging connected equipment, do not install magnetic
contactors on the output side of the inverter (motor side). Metal debris in the inverter
may cause inverter failure.

Installing the Inverter
To connect cables to the control terminals without using crimp terminals, refer to the
following illustration detailing the correct length of exposed conductor at the end of the
control cable.
Note
• While making wiring connections at the control terminals, ensure that the total cable
length does not exceed 165 ft (50 m).
• Ensure that the length of any safety related wiring does not exceed 100 ft (30m).
• Use ferrite material to protect signal cables from electro-magnetic interference.
• Take care when supporting cables using cable ties, to apply the cable ties no closer
than 6 inches from the inverter. This provides sufficient access to fully close the front
cover.
• When making control terminal cable connections, use a small flat-tip screw driver (0.1
in wide (2.5 mm) and 0.015 in thick (0.4 mm) at the tip).
26
Installing the Inverter
The Nx2000+ inverter supports both PNP (Source) and NPN (Sink) modes for
sequence inputs at the terminal. Select an appropriate mode to suit requirements
using the PNP/NPN selection switch (SW1) on the control board. Refer to the
following information for detailed applications.
Select PNP using the PNP/NPN selection switch (SW1). CM is the common ground
terminal for all analog inputs at the terminal, and P24 is 24 V internal source. If you
are using an external 24 V source, build a circuit that connects the external source (-)
and the CM terminal.
27
Installing the Inverter
Select NPN using the PNP/NPN selection switch (SW1). CM is the common ground
terminal for all analog inputs at the terminal, and P24 is 24 V internal source. Note
that the factory default setting is NPN mode.
28

Step 6 Disabling the EMC Filter for Power Sources with Asymmetrical
Grounding
Nx2000+, 400 V products do have built-in EMC filters. An EMC filter prevents
electromagnetic interference by reducing radio emissions from the inverter. EMC filter
feature is set to On by factory default. Current leakage increases when the EMC filter
feature is used.

• Do not activate the EMC filter if the inverter uses a power source with an asymmetrical
grounding structure, for example a grounded delta connection. Otherwise it may cause
an electrical shock and result in personal injury or even death.
• Before opening the cover to start working, wait at least 10 minutes after the power is
disconnected and check that the DC voltage of the product is discharged using a
tester. Otherwise it may cause an electrical shock and result in personal injury or even
death.
29
Installing the Inverter
Before using the inverter, confirm the power supply’s grounding system. Disable the
EMC filter if the power source has an asymmetrical grounding connection. Check the
location of the EMC filter on/off screw and attach the plastic washer to the screw
under the control terminal block.
After completing the wiring and basic configurations, assemble the front cover in order.
Note that the assembly procedure may vary according to the product group or frame
size of the product.

1 Turn on the power supply to the inverter. Ensure that the keypad display light is
on.
Note
If the forward command (Fx) is on, the motor should rotate counterclockWise when
viewed from the load side of the motor. If the motor rotates in the reverse direction,
switch the cables at the U and V terminals.
33
Installing the Inverter
• Check the parameter settings before running the inverter. Parameter settings may
have to be adjusted depending on the load.
• Do not supply the inverter with an input voltage that exceeds the rated voltage for the
equipment. This may cause damage to the inverter.
• Before running the motor at maximum speed, confirm the motor’s rated capacity. As
inverters can be used to easily increase motor speed, take caution to ensure that motor
speeds do not accidently exceed the motor’s rated capacity.

As a low-pass filter, use if there is significant variation of frequency
parameter setting value due to high noise level. When used, it filters the
analog signal to pass only the clean input signals. The higher the
number of time constant filter, the lower the variation in frequency.
In.07 V1 Filter
However this slows down the time t and thus affects the response time.
The value t (time) indicates the time required for the frequency to reach

These parameters are used to configure the gradient level and offset
values of the Output Frequency, based on the Input Voltage.
In.16 V1 Inverts the input value of V1. Set this code to 1 (Yes) if you need the
Inverting motor to run in the opposite direction from the current rotation.
Quantizing may be used when the noise level is high in the analog input
(V1 terminal) signal. The frequency is output by measuring (quantizing)
the height (value) of the input signal in a consistent interval. This means
that the delicate control on the output frequency (power resolution) is
low, but the noise is reduced, so it is suitable for systems that are
sensitive to noise.
In.17
V1 Quantizing Parameter values for quantizing refer to a percentage based on the
(Quantizing) maximum input. Therefore, if the value is set to 1% of the analog
maximum input of 10 V and maximum frequency of 60 Hz, the output
frequency will increase or decrease by 0.6 Hz per 0.1V difference.
60
Learning Basic Features
Code and

input signal value increases, the output frequency starts changing if the
height becomes equivalent to 3/4 of the quantizing value. From then on,
the output frequency increases according to the quantizing value. On
the other hand, when the input signal decrease, the output frequency
starts decreasing if the height becomes equivalent to 1/4 of the
quantizing value.
Although the noise can be reduced using the low-pass filter (In.07), the
response on the input signal takes long as the set value gets higher.
Since it becomes difficult to control the frequency if the input signal is
delayed, a period of long pulse (ripple) may occur on the output
frequency.

with dwell frequency before opening the mechanical brake of lift-type loads, such as
an elevator.

Note
Dwell operation does not work when:
• Dwell operation time is set to 0 sec or dwell frequency is set to 0 Hz.
• Re-acceleration is attempted from stop or during deceleration, as only the first
acceleration dwell operation command is valid.
• Although deceleration dwell operation is carried out whenever stop commands are
entered and the deceleration dwell frequency is passed through, it does not work
during a deceleration by simple frequency change (which is not a deceleration due to a
stop operation), or during external brake control applications.
When a dwell operation is carried out for a lift - type load before its mechanical brake is
released, motors can be damaged or their lifecycle reduced due to overflow current in the
motor.

• When measuring all parameters when motor is static after selecting 2[(All(Static type)]
at bA20 (auto tuning), the accuracy is rather less than the method of selecting 1 (ALL)
and measuring the parameters when the motor is rotating. This means that the
performance sensorless operation may be lowered. Therefore, run static type auto

• If operated within the rated output, the Nx2000+ series inverter is designed to withstand
instantaneous power interruptions within 15 ms and maintain normal operation. Based

interruption within 15ms is guaranteed for 200 V and 400 V inverters (whose rated
input voltages are 200–230 VAC and 380–460 VAC respectively).
• The DC voltage inside the inverter may vary depending on the output load. If the power

decelerates. Once the output frequency reaches brake engage frequency (BR Eng
Fr), the motor stops deceleration and sends out a brake engage signal to a preset

Additional stall protection levels can be configured for different

stall level can be set above the base frequency. The lower and upper
limits are set using numbers that correspond in ascending order. For
example, the range for Stall Frequency 2 (Stall Freq 2) becomes the
lower limit for Stall Frequency 1 (Stall Freq 1) and the upper limit for
Stall Frequency 3 (Stall Freq 3).
Note
Stall protection and flux braking operate together only during deceleration. Turn on the
third and fourth bits of Pr.50 (Stall Prevention) to achieve the shortest and most stable
deceleration performance without triggering an overvoltage fault trip for loads with high
inertia and short deceleration times. Do not use this function when frequent deceleration
of the load is required, as the motor can overheat and may be damaged easily.
When operating Brake resistor, the motor may vibrate under the Flux braking operation. In
this case, please turn off the Flux braking (Pr.50).
• Use caution when decelerating while using stall protection as depending on the load,
the deceleration time can take longer than the time set. Acceleration stops when stall
protection operates during acceleration.
• When the motor is operating, Stall Level 1 applies and determines the operation of stall

Note
A frequency set via communication using the common area frequency address (0h0380,
0h0005) is not saved even when used with the parameter save function. To save a
changed frequency to use after a power cycle, follow these steps:
215
RS-485 Communication Features
1 Set a frequency reference after setting the frequency reference source to 1 (Keypad-
1).
2 Set the frequency via communication into the parameter area frequency address
(0h1D04).
3 Perform the parameter save (0h03E0: '1') before turning off the power. After the
power cycle, the frequency set before turning off the power is displayed.
216
RS-485 Communication Features
Note
• When setting parameters in the inverter memory control area, the values are
reflected to the inverter operation and saved. Parameters set in other areas via
communication are reflected to the inverter operation, but are not saved. All set
values are cleared following an inverter power cycle and revert back to its previous
values.
Therefore, make sure to save the parameter after setting the parameter of a
different area as communication and before turning off the inverter power. But it is
not necessary to save the parameter at the inverter memory control area and the
value will be saved to the inverter immediately once the setup is complete.
• Define the parameter carefully. After setting a parameter to 0 via communication,
set it to another value. If a parameter has been set to a value other than 0 and a
non-zero value is entered again, an error message is returned. The previously-set
value can be identified by reading the parameter when operating the inverter via
communication.
• The addresses 0h03E7 and 0h03E8 are parameters for entering the password.
When the password is entered, the condition will change from Lock to Unlock, and
vice versa. When the same parameter value is entered continuously, the
parameter is executed just once. Therefore, if the same value is entered again,
change it to another value first and then re-enter the previous value.
For example, if you want to enter 244 twice, enter it in the following order: 244 → 0
→ 244.
It may take longer to set the parameter values in the inverter memory control area
because all data is saved to the inverter. Be careful as communication may be lost during
parameter setup if parameter setup is continues for an extended period of time.

Maintenance
10 Maintenance
This chapter explains how to replace the cooling fan, the regular inspections to
complete, and how to store and dispose of the product. An inverter is vulnerable to
environmental conditions and faults also occur due to component wear and tear. To
prevent breakdowns, please follow the maintenance recommendations in this section.
• Before you inspect the product, read all safety instructions contained in this
manual.
• Before you clean the product, ensure that the power is off.
• Clean the inverter with a dry cloth. Cleaning with wet cloths, water, solvents, or
detergents may result in electric shock or damage to the product.
271
Maintenance
272
Maintenance
273
Maintenance
Do not run an insulation resistance test (Megger) on the control circuit as it may result in
damage to the product. This may cause damage to the inverter.
274
Maintenance
10.2.1 Storage
If you are not using the product for an extended period, store it in the following way:
• Store the product in the same environmental conditions as specified for operation
(refer to 1.3 Installation Considerations on page 4).
• When storing the product for a period longer than 3 months, store it between -10
˚C and 30 ˚C, to prevent depletion of the electrolytic capacitor.
• Do not expose the inverter to snow, rain, fog, or dust.
• Package the inverter in a way that prevents contact with moisture. Keep the
moisture level below 70% in the package by including a desiccant, such as silica
gel.
• Do not leave the inverter in a humid or dusty environment (e.g. Used as a device or
control panel at a construction site). Disassemble the product and store in a place
that is suitable for operation.
275
Maintenance
10.2.2 Disposal
When disposing of the product, categorize it as general industrial waste. The product
contains materials that can be recycled. Please consider the environment, energy,
and resources and recycle unused products. The packing materials and all metal
parts can be recycled. Although plastic can also be recycled, it can be incinerated
under controlled conditions in some regions.
If the product is left in a prolonged state without a flow of current, the condenser will
deteriorate due to its characteristics. To prevent the deterioration of the electrolytic
capacitor, turn on the power of inverter at least once a year to apply a current for 30–60
seconds. Run the device under no-load conditions.

Installation
1 Remove the RJ45 terminal cover on the inverter I/O cover. Connect the remote
keypad cable to the I/O RJ45 connector.
2 Connect the other end of the connector of the remote keypad cable to the remote
keypad.
Enable
1 Once connected to the remote keypad, the key of the inverter keypad and the
button input of the jog controller are ignored. The input is replaced by the key and
volume input from the remote keypad.
• Within 2 seconds of detaching the remote keypad, the input for the key and
volume is reset to the inverter keypad. (If the frequency setting is set to volume
input, the command frequency will instantly switch between the inverter keypad
volume and the remote keypad volume when attaching and detaching. Take
care so that the motor does not switch to the wrong frequency.)
• If communication is not linked between the inverter and the remote keypad,
"E.vEr" is displayed on the 7-Seg of the remote keypad.
2 Set the dr 91 parameter to 4 in a state of connecting the remote keypad to copy
the parameter settings saved in the inverter to the remote keypad.
• “r-UL” is displayed on the inverter I/O 7-Seg keypad while upload is in progress.
“d” is displayed on the 7-Seg keypad of the remote keypad. After saving, the
message disappears and the default screen is displayed.
• If there is an error, such as poor communication while the upload is in progress,
a warning message saying "Fail" is displayed for 3 seconds, and the action of
saving the parameters into the remote keypad fails.
3 After connecting the remote keypad where the parameter settings are copied to
the inverter product of same model, set the dr 91 parameter to 5, and copy the
parameter settings saved in the remote keypad to the inverter.
• While saving, a message saying “W-dL” is displayed on the inverter I/O 7-Seg.
"U" is displayed on the 7-Seg of the remote keypad. After saving, the message
disappears and the default screen is displayed. If parameter data is not saved
in the remote keypad, you cannot set the dr 91 parameter to 5.
• If there is an error such, as poor communication with the remote keypad, a
warning message saying "Fail" is displayed for 3 seconds, and the action of
saving the parameters into the inverter fails.
• If the parameter code version or the inverter model is different (copying
parameters between 200V ⇄ 400V products), the WErr warning is displayed for
5 seconds, and the action of saving parameters into the inverter fails.
