2.3.5. 1-6* Load Depend. Setting
Parameters for adjusting the load-dependent motor settings.
1-60 Low Speed Load Compensation
Range: Function:
100%
*
[0 - 300%] Enter the % value to compensate voltage in relation to load
when the motor is running at low speed and obtain the optimum
U/f characteristic. The motor size determines the frequency
range within which this parameter is active.
Motor size
Change over
0.25 kW - 7.5 kW < 10 Hz
11 kW - 45 kW < 5 Hz
55 kW - 550 kW < 3-4 Hz
1-61 High Speed Load Compensation
Range: Function:
100%
*
[0 - 300%] Enter the % value to compensate voltage in relation to load
when the motor is running at high speed and obtain the opti-
mum U/f characteristic. The motor size determines the frequen-
cy range within which this parameter is active.
Motor size
Change-over
0.25 kW - 7.5 kW > 10 Hz
11 kW - 45 kW < 5 Hz
55 kW - 550 kW < 3-4 Hz
1-62 Slip Compensation
Range: Function:
0%
*
[-500 - 500 %] Enter the % value for slip compensation, to compensate for tol-
erances in the value of n
M,N
. Slip compensation is calculated
automatically, i.e. on the basis of the rated motor speed n
