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 wiring of the temperature sensor.

Subfault: 31.3 Description: Temperature sensor overtemperature – motor 1
	Response: Output stage inhibit
Cause	Measure
Temperature sensor of motor 1 signals overtemperature.	– Allow the motor to cool down. – Check for motor overload. – Check whether the correct temperature sensor KY (KTY) was parameterized instead of PK (PT1000).

Subfault: 31.3

Description: Temperature sensor overtemperature – motor 1

Response: Output stage inhibit

Cause

Measure

Temperature sensor of motor 1 signals overtemperature.

– Allow the 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 overtemperature.	– Allow the 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 overtemperature.

– Allow the motor to cool down.

Subfault: 31.7 Description: UL temperature monitoring
	Response: Output stage inhibit
Cause	Measure
Temperature model of active motor signals overtemperature.	Check for motor overload.

Subfault: 31.7

Description: UL temperature monitoring

Response: Output stage inhibit

Cause

Measure

Temperature model of active motor signals overtemperature.

Check for motor overload.

Subfault: 31.8 Description: Communication timeout temperature sensor – motor 1
	Response: Output stage inhibit
Cause	Measure
Communication with temperature sensor is disrupted, e.g. via MOVILINK^® DDI.	Check the cabling.

Subfault: 31.8

Description: Communication timeout temperature sensor – motor 1

Response: Output stage inhibit

Cause

Measure

Communication with temperature sensor is disrupted, e.g. via MOVILINK^® DDI.

Check the cabling.

Subfault: 31.9 Description: Temperature too low at temperature sensor – motor 1
	Response: Output stage inhibit
	Cause	Measure
	Short circuit in connection with temperature sensor of motor 1. For long cables, a short circuit can be misinterpreted as a voltage value of a low temperature.	Check the wiring of the temperature sensor.
	Temperature signaled by temperature sensor of motor 1 below -50 °C.	– Check if a KTY temperature sensor is installed in the motor but the parameterization has been carried out for a PT1000 temperature sensor. – Heat the motor.
