They have a minimum frequency that they can work at, they will fail if the frequency gets to low
The IGBT's used to blow, all the time,( repaired lots of them ) they have made the IGBT much more robust than they where, so now this looks like the weak link, yes the sensor can be damaged if the processor can't control /balance the Frequency and Amps
A Parameter setting of 20Hz or less and this sensor will fail, as it can't control at these low Frequencies
