Terminal Module 31

A Terminal Module 31 (TM31) is used when additional digital and analog inputs/outputs
required. The temperature sensor is connected at terminal X522. The values of the fault
and/or alarm thresholds can be set in parameter p4102[0..1] from -48 °C to 251 °C.
p4102 = 251°C deactivates the alarm and fault threshold. The factory setting is 100 °C for
the alarm threshold and 120 °C for the fault threshold.
Temperature measurement
● p0600 = 10 activates the motor temperature measurement via the external sensor.
● p0603 sets the signal source for the evaluation of the motor temperature
● p4100 = 0 disables the evaluation. Then parameter r4105 = -300°C.
