Connections for temperature sensor (motor interface 1)
53
Temp 1
Sensor acc. to p50490
The cable to the temperature sensor on the motor must be shielded
and connected to ground at both ends.
The cables for the Temp 1 and Temp 3 connections to the temperature
sensor must have approximately the same length.
The sense cable (Temp 2) is used for compensating the cable
resistances. If you are not using a sense cable, terminals 54 and 55
must be connected.
