Motor wires typically have connections for phases and
for grounding the motor’s frame.
The grounding wire is commonly colored green with a yellow stripe. This should
connect to the ground terminal of the motor connector. There should be a connection
between the PE (Protective Earth) terminal to an earthed grounding point. PE and
Ground are connected in the drive. This wiring ensures that the motor frame will
always be at ground potential. Using shielded cable which connects to the motor frame
and earth ground close to the drive provides a return path for currents induced in the
shield and motor by the PWM outputs. P-clamps provide the best way to ground the
shield for high-frequency noise suppression.
