The motor cable is highly susceptible to interference. For this
reason you achieve an optimum wiring on the motor side, if you
l use shielded and low-capacity motor cables only.
l do not incorporate further cables in the motor cable (e.g. for
brake control, external fans etc.).
l shield the cable for temperature monitoring of the motor (PTC
or thermal contact)and separate it from the motor cable.
In special cases it is possible to incorporate the cable for motor temperature
monitoring in the motor cable.
