CAUTION

Instructions for safe and correct operation

1. The capacity of the power source must be in the range 1.5 times the inverter capacity to 500
kVA. If the power source has 500 kVA or higher capacity and the length of the cable
between it and the inverter is 100 m or less, or if the power source has a phase advancing
capacitor selector, excessive peak current will flow into the power source input circuit and
may damage the converter. If this is the case, install power factor improvement AC reactor
at the input of each inverter.

2. Do not connect the phase advancing capacitor to the inverter output. Otherwise, the
capacitor may be damaged.

3. Do not install an electromagnetic contactor between the inverter and motor. Run/stop the
motor from inverter operation panel using the RUN switch or control input terminal. Do not
operate the electromagnetic contactor installed on the power source more often than
actually required.
In particular, never attempt to start or stop the motor with this electromagnetic contactor.

4. Operating the motor through the inverter increases leakage current that may trip the leakage
breaker. If this is the case, use leakage breaker of high frequency proof type (designed for
use with inverter) on both the system causing the problem and system affected.

5. The total cable length of the inverter and motor must be shorter than 30 m. To use a cable
longer than 30 m, provide a reactor between the inverter and the motor, or reduce the
inverter’s carrier frequency.

Inverter ↔ motor cable length

[ Carrier frequency]

Up to 30 m Up to 50 m Up to 100 m

0 to 7

(14.9 kHz or less)

0 to 5

(10.1 kHz or less)

0 to 2

(3.9 kHz or less)

6. To use the electronic thermal trip function incorporated in the inverter, observe the following

instructions.

• Check the rated current of your 3-phase induction motor to define the electric thermal

value.

• Use one motor for each inverter.

7. To control several motors with an inverter (parallel operation), select the inverter’s capacity

so that the total of the motors’ rated currents does not exceed the inverter’s rated current.
Note that, if you select the inverter’s capacity based on the total of the motors’ capacity, the
inverter’s rated current may be exceeded depending on the motor type.

System Configuration and Wiring

Changing the input signal logic

The inverter provides two types of input signal logics: sink input and source input.

When the “PLC” and “12 V” terminals are short-circuited, sink input is available. When the “PLC”
and “G” terminals are short-circuited, source input is available.

The inverter has been set for sink input before shipment.
The following description is provided on the assumption that the inverter has been set for
sink input.

1) Sink input

This logic indicates that a signal turns ON when a current flows out of an input terminal.
“G” is the common terminal for input signals.

System Configuration and Wiring

Precautions when wiring

Internal circuits retain high voltage for a certain period time after power is off. Wait at least for
15 minutes after power off before starting any wiring.

Main circuit

(1) If the power supply terminals (R/L1, S/L2 and T/L3) and motor terminals (U/T1,

V/T2 and W/T3) are connected in reverse, the inverter will be damaged. Be

sure not to connect these terminals in reverse.
(2) Do not ground the main circuit terminal.
(3) Do not short-circuit the motor terminals (U/T1, V/T2 and W/T3).
(4) The ground (E) terminal is the inverter’s frame ground terminal.
(5) To connect the main circuit terminal, be sure to use a crimp terminal with

insulation sheath.
(6) To run the inverter, use the no-fuse breaker (NFB) according to the standard

connection diagram.

Select a no-fuse breaker according to the motor ratings.
(7) Be sure to remove the phase advancing capacitor from an existing motor.

Control circuit

(1) When connecting a control circuit conductor, strip off a suitable length of insulation: too

long bare conductor will touch with another conductor; too short bare conductor will
easily pull off the connection. When connecting two more conductors together, twist
them before wiring or connecting.

(2) When using a bar terminal or solid conductor, select one having a diameter equal to 0.9

mm or less. Fastening screw may be damaged.

(3) Do not apply more than 24 VDC, 50 mA to the output terminals (COM1, O1, O2), or

apply voltage to terminal in reverse.

Do not apply 30 VAC, 2 A (or 30 VDC, 2 A) to the output terminals (COM2, NO and NC).
(4) Do not apply an external voltage to the input terminals (I1 to I6).
(5) Do not short-circuit the frequency setting power supply terminal (5 V) and the external

power supply terminal (12 V) with the control ground (G) terminal.
(6) To directly drive the relay by the output terminals (COM1, O1, O2), mount a flywheel diode

(FD).

Pay attention to polarity of diode.

(7) For connections to the control circuit, use twisted cables or shielded cables.
(8) The cable connected to the control circuit must be placed apart from a power cable.
(9) To tighten a cable, put a screwdriver on the terminal perpendicularly.

Operation Function

Operation function

The inverter has the following control functions that are made active from the operation
panel and terminal block.

Operation control

Jogging

Free-run stop

DC brake

Positioning DC

brake

Acceleration/deceleration time is set to “0”. This function is optimum for

positioning. By setting [ Operation mode selection] to “2-speed mode”,
jogging operation is enabled.
When the “I3” and “G” control input terminals are short-circuited, CCW
jogging is enabled. When “I4” and “G” are short-circuited, CW jogging is
enabled, and the jogging frequency is output.
You can switch over between the normal operation mode and the jogging
mode.
The jogging frequency can be specified in the range of 0 to 30 Hz. If the
jogging frequency is too high, the inverter may trip due to overcurrent.

Turns off the output voltage applied to the motor, allowing the motor to coast.

This function is useful to brake the motor mechanically. Remember that
touching the motor output terminals (U/T1, V/T2 and W/T3) may cause
electric shock even if the free-run stop function is activated.

Activates the brake by applying a direct current to the motor at the time

when the inverter shifts from the running status to the stop status. If the
CCW, CW or jogging command is issued while the DC brake function is
activated, the DC brake is disabled, and the motor starts running as
specified by the command.

When a stop command is issued during normal operation, the motor

soft-stops, and the DC brake is activated when the output frequency is
reduced to 3 Hz. (The frequency at which the brake is activated can be
changed with the parameter).

Description

DC brake for

full-range stop

When the frequency is set to “0”, the DC brake is activated when the output

frequency falls below 1 Hz.

The DC brake intensity (torque) and time can be specified with the

parameters.

When a stop command is issued during normal operation, the DC brake is

immediately activated without soft-stop.

The DC brake intensity (torque) and time can be specified with the

parameters.

The DC brake time is twice as long as the time specified for “Positioning DC

brake”.

■ Input terminal description

(1) Input terminals are given the following priority.

DC brake < Normal operation < Jogging < Free-run stop < External forced trip

Example)

① If the run command is issued while the DC brake is activated, the motor

will immediately start running.

② If the free-run stop command is issued during jogging operation, the

motor will coast to stop.

③ Even if the run command is issued while the free-run command is

activated, the motor will not start running.

(2) If both the CCW and CW commands are issued during trip, the trip can be

canceled. Before canceling the trip, remove the cause of the trip.

Maintenance/Inspection

You should perform maintenance/inspection on a regular basis in order to ensure safety
and keep the inverter in good running order.

Precautions when performing maintenance/inspections

(1) The power should be turned on/off only by the person performing the task.
(2) The internal circuits of the inverter remain charged with high voltage for a short

while after power is turned off. To perform inspection, first turn off the power and
then wait for the LED display on the operation panel to go off (min. 15 minutes).

(3) Do not use a megger for the purpose of measuring insulation resistance.

Otherwise, the inverter is damaged.

Conformity to EC Directive / UL Standard

EC Directive

The EC Directive is applied to all electronic products that provide proper functions and are exported to

EU (European Union) for direct sales for general consumers. These products must conform to the EU

uniformed safety standards, and the CE marking that indicates the conformity to the standards must be

affixed to the products.

Inverters are handled as the components to be incorporated in machinery or equipment, not the

above-mentioned product that provides proper functions and are exported for direct sales for general

consumers. Therefore, applying the CE marking to inverters is not compulsorily required.

To facilitate the conformity of the machinery or equipment that incorporates inverters to the EC Directive,

we attain conformity to the relevant standards of the Low Voltage Directive.

Conformity to the EMC Directive

Regarding our inverter systems, we define models (conditions) of their installation distance, wiring and

so on for inverters and general-purpose motors, so that the models conform to the relevant standards of

the EMC Directive. However, when an inverter system is actually incorporated in machinery or

equipment, its wiring and grounding conditions may be different from the models. For this reason, the

machinery or equipment in which the inverter and general-purpose motor are incorporated must

undergo the final examination to verify the conformity to the EMC Directive (particularly, in terms of

unnecessary radiation noise and noise terminal voltage).
