0 Mode motor resistance and inductance measurement
0: No measurement

2 Reserved
3 Mode of the adaption of the dead time compensation after the PWM fre-
quency:
0: Not activated
1: Activated
4 Motor diagnosis:
0: Not activated
1: Activated
The motor diagnosis will be initiated if only bit 4 is activated and all other
bits were deactivated.
– If the adaption is requested, the bit must be set before the measurement and then
must remain the same.
– If the bit is changed, the dead time voltage measurement must be repeated.
– If the adaption is activated, the dead time measurement values are converted to val-
ues corresponding to a PWM frequency of 8 kHz and subsequently stored in the
dead time correction table Z123.15–. The effective dead time voltage for the dead
time compensation is adapted according to the presently used switch frequency.
This can be different to the switch frequency at the moment of the measurement.
Better dead time compensation is reached if the used switch frequency and switch
frequency at the time of measurement are equal.
