Fault 11 Temperature monitoring

Subfault: 11.1 Description: Heat sink overtemperature
	Response: Emergency stop + output stage inhibit
Cause	Measure
Maximum permitted heat sink temperature exceeded. The capacity utilization is possibly too high.	– Reduce the load. – Reduce the rms value of the current. – Reduce the PWM frequency. – Ensure sufficient cooling. – Reduce the ambient temperature.
