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 an output filter. The motor cable length is then solely limited by the voltage drop on the motor cable.

INFORMATION

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