Manual MSX
6.5 Motor Cable
We recommend wiring the stepper motor with a 5-lead cable with shielding mesh. For
optimum electromagnetic compatibility (EMC), additional connectors or screw terminals
should not interrupt the cable.
The protective earth wire (green/yellow) of the motor cable should be connected to the
earthing screw near the motor connector of the MSX
green/yellow wire should be connected to the motor's earthing screw at the other motor
cable end.
