Temperature Sensor Evaluation - Siemens SINAMICS G150 Operating Instructions Manual

Temperature measurement via PT100
The connection is made at the terminals X41:3 (Temp-) and X41:4 (Temp+) at the Control
Interface Module. p0624 can be used to set the temperature offset for the PT100 measured
value.
● Activate motor temperature measurement via Motor Module: p0600 = 11.
● Set the PT100 temperature sensor type: p0601 = 5

Temperature sensor evaluation

Temperature measurement via KTY or PT100
● When the alarm threshold is reached (set via p0604; delivery state after commissioning
● When the fault threshold is reached (set via p0605, delivery state after commissioning
Temperature measurement via PTC or bimetallic normally closed contact
● Once the PTC or the bimetallic normally closed contact responds, alarm A07910 is
● Fault F07011 is triggered once the waiting time defined in p0606 has elapsed.
Sensor monitoring for wire breakage/short-circuit
If the temperature of the motor temperature monitor is outside the range -140 to +250 °C,
then the sensor cable is broken or has a short-circuit – and Alarm A07015 "Motor
temperature sensor alarm" is triggered. Fault F07016 ("Drive: Motor temperature sensor
fault") is triggered once the waiting time defined in p0607 has elapsed.
Fault F07016 can be suppressed using p0607 = 0. If an induction motor is connected, the
drive continues operating with the data calculated in the thermal motor model.
If the system detects that the motor temperature sensor set in p0600 is not connected, alarm
A07820 "Temperature sensor not connected" is triggered.

120 °C), alarm A07910 is triggered.
Parameter p0610 can be used to set how the drive responds to the alarm triggered:
– 0: No response, only alarm, no reduction of I_max
– 1: Alarm and reduction of I_max and fault (F07011)
– 2: Alarm and fault (F07011), no reduction of I_max
155 °C), fault F07011 is triggered in conjunction with the setting in p0610.
