2.3.5. 1-6* Load Depend. Setting
Parameters for adjusting the load-dependent motor settings.
1-60 Low Speed Load Compensation
Range:
100%
1-61 High Speed Load Compensation
Range:
100%
1-62 Slip Compensation
Range:
*
0%
Use this par. along with par. 1-50. See drawing for par. 1-50.
Function:
* [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.
Function:
* [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.
Function:
[-500 - 500 %] Enter the % value for slip compensation, to compensate for tol-
erances in the value of n
automatically, i.e. on the basis of the rated motor speed n
