Check
Saliency
In sensorless mode, when the motor speed is below Pr 00.045 / 10, a
special low speed algorithm must be used to control the motor. There
are two modes available, with the mode chosen based on the saliency of
the motor. The ratio No-load Lq (Pr 00.056) / Ld (Pr 05.024) provides a
measure of the saliency. If this value is > 1.1, then Non-salient mode
must be used (this is the default), otherwise Injection mode may be
used. Set Pr 00.054 for the selected mode: Injection (0) or Non-salient
(1).
