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.

Test Operation

Pre-operation inspections

After installing and wiring, inspect the following before running the inverter. (1) Check if wiring is correct. (In particular, check improper connections of the power

supply terminals (R/L1, S/L2 and T/L3) and motor terminals (U/T1, V/T2 and W/T3),

short-circuited load and ground fault.) (2) Does input power comply with the rating? (3) Are there any places that could be shorted by wire cuttings, etc? (4) Are any screws or terminals loose?

Test run

(1) Preparation for safety operation

① Set the motor so that it can be independently operated. ② Turn off all the inputs on the control terminal block.

(2) Follow the test procedure:
