2.10.4 Motor cable (U/V/W/PE)
The motor cable must have a
maximum length of 150m
(Please note also Chapter 8.4 EMC limit value classes). If a shielded
motor cable is used, or the metallic cable duct is well earthed, the
maximum length of 50m
should not be exceeded. For longer
cable lengths , additional output chokes must be used.
For multiple motor use, the total cable length consists of the sum of the individual cable lengths. If the sum of the cable lengths
is too high, one output choke should be used per motor/cable.

brake resistor should be shielded and as short as possible.
Note:
Possible strong heating of the brake resistor should be taken into account.
