Motor cable lengths

If a motor cable length of 100 m is exceeded for an individual device up to and including size 3, the DC link choke must not be dispensed with. The same applies to multi-motor or group drives if the sum of the motor cable lengths exceeds 100 m.

Note the sum of the motor cable lengths of all devices connected to the regenerative power supply. This must not exceed the values in the following table.
