Motor cable
If the motor cables are in-house produced, cable cross-sec-
tion, cable length and shielding have to be considered.
The cable cross-section has to be adapted to the phase cur-
rent. The cable cross-section should be calculated based on
the maximum phase current per motor phase.
For cables longer than 4m it can be necessary to adapt cable
losses by a modified configuration of the motor parameters
setumotmin and setumotgrad.
For the EMC-compatible fitting of the cable, a total shielding
is prescribed whereby the cable shield is connected to the
housing.
The DSUB-9 motor connector should have a metal case. The
fasten nuts of the DSUB connectors of the controller are
equipped with an UNC4-40 thread.
Upon request we manufacture motor cables according to
customer´s demands.
An incorrect wiring of the motor connection can damage
the controller.
