Subfault: 31.2
Description: Temperature sensor short circuit – motor 1
Response: Application stop + output stage inhibit
Cause
Measure
Short circuit in connection with temperature
sensor of motor 1.
Check the temperature sensor wiring.
Subfault: 31.3
Description: Temperature sensor overtemperature – motor 1
Response: Output stage inhibit
Cause
Measure
Temperature sensor of motor 1 signals overtem-
perature.
– Allow motor to cool down.
– Check for motor overload.
– Check whether the correct temperature sensor
KY (KTY) was parameterized instead of PK
(Pt1000).
Subfault: 31.4
Description: Temperature model overtemperature – motor 1
Response: Output stage inhibit
Cause
Measure
Temperature model of motor 1 signals overtem-
perature.
– Allow motor to cool down.
– Check for motor overload.
– Check whether the correct temperature sensor
KY (KTY) was parameterized instead of PK
(Pt1000).
Subfault: 31.5
Description: Temperature sensor prewarning – motor 1
Response: Thermal motor protection 1 – prewarning threshold
Cause
Measure
Temperature signaled by temperature sensor of
motor 1 exceeds prewarning threshold.
Check for motor overload.
Subfault: 31.6
Description: Temperature model prewarning – motor 1
Response: Thermal motor protection 1 – prewarning threshold
Cause
Measure
Temperature signaled by temperature model of
motor 1 exceeds prewarning threshold.
Check for motor overload.
