NOTE
Any signal cables which are carried inside the motor cable (i.e. motor
thermistor, motor brake) will pick up large pulse currents via the cable
capacitance. The shield of these signal cables must be connected to
ground close to the point of exit of the motor cable, to avoid this noise
current spreading through the control system.

NOTE
The SAFE TORQUE OFF drive enable terminal is a positive logic input
only. It is not affected by the setting of Input Logic Polarity (08.029).
