E6581160

Note 1. Capacity is calculated at 220V for the 240V models, at 440V for the 500V models and at 575V for the 600V models. Note 2. Indicates rated output current setting when the PWM carrier frequency (parameter F300) is 4kHz or less. When

exceeding 4kHz, the rated output current setting is indicated in the parentheses. It needs to be further reduced for PWM carrier frequencies above 12 kHz.

The rated output current is reduced even further for 500V models with a supply voltage of 480V or more. The default setting of the PWM carrier frequency is 12kHz.

Note 3. Maximum output voltage is the same as the input voltage. Note 4. ±10% when the inverter is used continuously (load of 100%).

Note 5. If you are using 600V model, be sure to connect an input reactor (ACL).

specifications

(programmable)

signal output, specified speed reach signal output and failure signal output, to assign to FL relay output, open

 

 

 

collector output and RY output terminals.

 

 

Jog run

Jog mode, if selected, allows jog operation from the operation panel or the terminal board.

 

 

 

Forward/reverse run

The RUN and STOP keys on the operation panel are used to start and stop operation, respectively. The switching

 

 

 

 

between forward run and reverse run can be done from one of the three control units: operation panel, terminal

 

 

 

 

board and external control unit.

 

 

 

 

 

 

 

Operation

Preset speed operation

Base frequency + 15-speed operation possible by changing the combination of 4 contacts on the terminal board.

activated. 10 times (Max.) (selectable with a parameter)

 

 

 

settings

panel for operation, emergency stop or resetting.

 

 

 

Regenerative power ride-

Possible to keep the motor running using its regenerative energy in case of a momentary power failure (default:

 

 

 

through control

OFF).

 

 

 

Auto-restart operation

In the event of a momentary power failure, the inverter reads the rotational speed of the coasting motor and outputs

 

 

 

 

a frequency appropriate to the rotational speed in order to restart the motor smoothly. This function can also be

 

 

 

 

used when switching to commercial power.

 

 

 

Drooping function

When two or more inverters are used to operate a single load, this function prevents load from concentrating on one

 

 

 

 

inverter due to unbalance.

 

 

 

Override function

The sum of two analog signals (VIA/VIB) can be used as a frequency command value.

 

 

 

Failure detection signal

1c-contact output: (250Vac-0.5A-cosφ=0.4)
