Subfault: 29.2
Description: Negative limit switch hit
Response: HW limit switches – current drive train
Cause Measure
Negative hardware limit switch hit – Check hardware limit switch wiring.
– Check target position.
– Move clear with positive speed.
Subfault: 29.3
Description: Limit switch missing
Response: Emergency stop + output stage inhibit
Cause Measure
Both limit switches (positive and negative) hit at the same time – Check hardware limit switch wiring.
– Check the parameter setting of digital inputs.
– Check the parameter setting of PO data.
Subfault: 29.4
Description: Limit switches reversed
Response: Emergency stop + output stage inhibit
Cause Measure
Positive hardware limit switch hit at negative speed, or negative
hardware limit switch hit at positive speed.
Check whether hardware limit switch connections are
swapped.
6.5.24 Fault 30 SW limit switch
Subfault: 30.1
Description: Positive limit switch hit
Response: SW limit switches – current drive train
Cause Measure
The positive software limit switch was hit. – Check software limit switch position.
– Check target position.
– Move clear with negative speed.
Subfault: 30.2
Description: Negative limit switch hit
Response: SW limit switches – current drive train
Cause Measure
– Negative software limit switch hit. – Check software limit switch position.
– Check target position.
– Move clear with positive speed.
Subfault: 30.3
Description: Limit switches reversed
Response: Emergency stop + output stage inhibit
Cause Measure
Position value of negative software limit switch greater than po-
sition value of positive software limit switch
Check software limit switch positions.
6.5.25 Error 31 Thermal motor protection
Subfault: 31.1
Description: Temperature sensor wire break – motor 1
Response: Application stop + output stage inhibit
Cause Measure
Connection to temperature sensor of motor 1 interrupted. Check temperature sensor wiring.
Subfault: 31.2
Description: Temperature sensor short circuit – motor 1
Response: Application stop + output stage inhibit
Cause Measure
Short circuit in the connection to the temperature sensor of mo-
tor 1.
Check temperature sensor wiring.
