Subfault: 11.7
Description: Wire break at temperature sensor of the heat sink
Response: Output stage inhibit
Cause Measure
Wire break at temperature sensor of the heat sink. Contact the SEW-EURODRIVE Service.
Subfault: 11.8
Description: Short circuit on the temperature sensor of the heat sink
Response: Output stage inhibit
Cause Measure
Short circuit on the temperature sensor of the heat sink. Contact the SEW-EURODRIVE Service.
6.5.10 Fault 12 Brake
Subfault: 12.1
Description: Brake output
Response: Application stop + output stage inhibit
Cause Measure
No brake connected Check the connection of the brake.
Brake cable disconnected in switched on state Check the connection of the brake.
Overload due to overcurrent > 2A Check the sequential profile of the brake control.
Overload due to excessive connection (> 0.5Hz) Check the sequential profile of the brake control.
Monitoring works only with parameter setting "Brake installed"
and "Brake applied".
Make sure that the connected brake is permitted.
Subfault: 12.2
Description: DC 24 V brake voltage
Response: Application stop + output stage inhibit
Cause Measure
DC 24V supply voltage not within permitted tolerance of ±
10%.
Check DC 24 V supply voltage.
Monitoring is only active with parameter settings “Brake in-
stalled” and “Brake applied”.
Check parameter setting.
6.5.11 Fault 13 Encoder 1
Subfault: 13.1
Description: Position comparison check
Response: Encoder 1 – latest critical fault
Cause Measure
Faulty comparison between raw position and track counter of
absolute encoders
– Check the track signal wiring.
– Check interference source (e.g. from EMC).
– Replace encoder.
– Replace card.
Note: In "emergency mode" manual mode, you can move the
drive using the motor encoder if the external position encoder
is faulty.
Subfault: 13.2
Description: Unknown encoder type
Response: Encoder 1 – latest critical fault
Cause Measure
Encoder type not known and not supported by inverter. – Check encoder type.
– Contact the SEW-EURODRIVE Service.
Note: In "emergency mode" manual mode, you can move the
drive using the motor encoder if the external position encoder
is faulty.
