FAILURE POSSIBLE CAUSES
The Current regulator selftune procedure never finishes and continues over and over again.
Because of the motor inductance value, the routine is executing an endless loop. The
inductance value is cycling between two values without an evolution of the
algorithm.
Solution procedure:
1) verify the two displayed inductance values
2) insert the average value as motor inductance during the autotuning.
If the procedure does not end, repeat step 1) and 2).
