DANGER!
For safety reasons, all PE ground conductors must be connected prior to initial
operation.
The EN 50178 regulations for protective earthing must be complied with during
installation!
7.1 Operation with long motor cables
In applications involving long motor cables and/or unsuitable motor cables with an inadvertently high
cable capacity, the filters may be thermally overloaded. To avoid such problems we highly recommend
the following procedure for applications that require long motor cables:
As of a cable length of more than 25 m, only use cable with less than 150 pF/m (capacitance per
unit length) between the motor phase and the shield!
(Please contact your motor cable supplier if necessary).
Lower the power stage clock frequency when using cable lengths of 25 m or longer.
Both measures are also good for the EMC behavior of the entire drive:
The servo positioning controller generates less and less severe interference and the emission of
interference into the mains is reduced.
