Motor temperature monitoring (TM+, TM)
Connections TM+ and TM- are used to evaluate the temperature of
connected Rexroth motors. These are equipped with a temperature-
dependent resistor (either PTC or NTC dependent on the motor type) to
monitor temperature. The connection leads are in the motor power cable.
