6.10.4 Motor cable length
The maximum motor cable length depends on:
• Cable type
• Voltage drop in the cable
• Set PWM frequency.
• Using an output filter
The limit values in the tables do not apply if you use and output filter. The motor cable
length is then solely limited by the voltage drop on the motor cable.

NOTE
Do not use an earth-leakage circuit breaker with long motor cables. The leakage
currents caused by cable capacitance may cause mis-tripping.
