171
Subfault: 10.11
Description: No application program loaded
Response: Output stage inhibit
Cause Measure
No data flexibilization layer application program loaded Load the program or disable the data flexibilization layer.
Subfault: 10.99
Description: Unknown error
Response: Application stop + output stage inhibit
Cause Measure
Unknown data flexibilization layer error Contact the SEW-EURODRIVE Service.
6.5.9 Fault 11 Temperature monitoring
Subfault: 11.1
Description: Heat sink overtemperature
Response: Output stage inhibit
Cause Measure
Maximum permitted heat sink temperature exceeded The ca-
pacity utilization is possibly too high.
– Reduce the load.
– Reduce the rms current value
– Reduce the PWM frequency.
– Ensure sufficient cooling.
– Reduce the ambient temperature.
Subfault: 11.2
Description: Heat sink utilization – prewarning
Response: Heat sink utilization – prewarning
Cause Measure
High thermal load on heat sink of device, and prewarning
threshold reached.
– Reduce the load.
– Reduce rms value of output current.
– Reduce the PWM frequency.
– Ensure sufficient cooling.
– Reduce the ambient temperature.
Subfault: 11.3
Description: Device utilization
Response: Output stage inhibit
Cause Measure
The temperature has reached or exceeded the switch-off
threshold. Possible causes: Mean output current too high.
Reduce the load.
PWM frequency too high. Reduce PWM frequency.
Ambient temperature too high. Ensure sufficient cooling.
Unfavorable air convection Check air convection.
Fan defective Check fan and replace if necessary.
Subfault: 11.5
Description: Electromechanical utilization
Response: Output stage inhibit
Cause Measure
Electromechanical components of device overloaded by ex-
cessive continuous current.
Reduce the load. If necessary, reduce the rms value of the cur-
rent.
Subfault: 11.6
Description: Electromechanical utilization – prewarning
Response: Electromechanical utilization – prewarning
Cause Measure
High load on electromechanical components of device due to
high continuous current. Prewarning threshold reached.
– Reduce the load.
– Reduce the PWM frequency.
– Reduce the rms current value
– Reduce the ambient temperature.
