Motor cable
We recommend wiring the stepper motor with a 5-lead cable with shielding mesh. For
optimum electromagnetic compatibility (EMC), the cable should not be interrupted by
additional connectors or screw terminals.
The PE conductor (green/yellow) of the motor cable is connected to the PE contact of the
5-pole motor plug. On the motor side, the PE conductor must be connected to the earthing
screw of the motor.
The motor cable length depends on the cable resistance: R
