Integration

Maximum permissible cable lengths from the motor to the

inverter when using output reactors or sine-wave filters

depending on the voltage range

The following load-side power components in the appropriate

frame sizes are optionally available for the Power Modules and

result in the following maximum cable lengths:

Derating data

The following inverter output currents can still be implemented

for long motor cables without output reactor and sine-wave filter.

Derating for PM250 Power Modules, frame sizes FSC to FSF for

shielded motor cables. From frame size FSD and higher, only the

particular main Power Module types were tested. The values

also apply to the other Power Modules of the particular frame

size.
