4.2.4. 1-6* Load Dependent setting
Parameters for adjusting the load dependent motor settings.
1-60 Low Speed Load Compensation
Range: Function:
Use this parameter to gain optimum U/f characteristic when running at low speed.
100 %
*
[0-199 %]
Enter percentage in relation to load when motor runs at low speed.
Change-over point is automatically calculated based on motor size.
1-61 High Speed Load Compensation
Range: Function:
Use this parameter to obtain optimum load compensation when running at high speed.
100 %
*
[0 - 199 %]
Enter percentage to compensate in relation to load when motor runs at high speed.
Change-over point is automatically calculated based on motor size.
1-62 Slip Compensation
Range: Function:
100 %
*
[-400 - 399 %]
Compensation for load dependent motor slip.
Slip compensation is calculated automatically based on rated motor speed, n
M,N
.
NB!
This function is only active when par. 1-00,
Configuration Mode
, is set to
Speed Open Loop
[0], and when par. 1-01,
Motor Control Principle
, is set to
VVC+
[1].
1-63 Slip Compensation Time
Range: Function:
0.10 s [0.05 - 5.00 s] Enter slip compensation reaction speed. A high value results in slow reaction whereas a low value results in quick
reaction.
If low-frequency resonance problems arise, use longer time setting.
