When switching on the motor side, the switching units must be rated for DC
voltages.

- If you only switch when no voltage is applied, e.g. electrical latching via
controller inhibit, you can also use standard AC switching units.
Note!
-
When switching with controller enabled, the fault indication ”OCx”
(short-circuit/earth fault during operation x) can be activated.
-
When using long motor cables and controllers with low output power,
leakage currents via parasitic cable capacities can activate the fault
indication ”OCx”.
- In such a case, motor filters or sine filters should be used.
- Further information on long motor cables for stand-alone and group drives
can be obtained from the corresponding application reports.
