Examples in regard to constant speed and moderate discrepancies in the motor parameters:
a) Too low without adaption and breakdown limit: Voltage limit Value is lower than calculated;
b) Including adaption although there are discrepancies, Value of the voltage limit as calculated:
Breakdown limit okay.;
c) Without adaption and breakdown limit is too high: Value of the voltage limit is higher than calculat-
