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.

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.

Range: Function:
0%
*
[-500 - 500 %] Enter the % value for slip compensation, to compensate for tol-
