Parameter 1-60 Low Speed Load
Compensation has no effect
when parameter 1-10 Motor
Construction = [1] PM, non-
salient SPM.
Enter the % value to compensate
voltage in relation to load when the
motor is running at low speed, and
obtain the optimum U/f charac-
teristic. The motor size determines
the frequency range within which
this parameter is active.
