1)
Overvoltage protection elements must be connected for cable lengths that are longer than 30m.
2)
Shielding is not required if the cables are not longer than 1 m or they are routed close to the rear panel
of the metal control cabinet.
3)
Longer motor cables are possible if the output current reduction is taken into consideration or motor
reactors are used.

• "Technical data (Page264)"
4.11.2 Con󹪝guring the Motor Modules depending on the cable length
Description
If you require a longer motor connection cable than your Motor Module permits, then you must
select a larger Motor Module or reduce the permissible continuous output current I
continuous
in
relation to the rated output current I
rated
.
