[4] [5]
Function:
Use this parameter to gain optimum U/f characteristic when running at low speed.
Enter percentage in relation to load when motor runs at low speed.
Change-over point is automatically calculated based on motor size.
Function:
Use this parameter to obtain optimum load compensation when running at high speed.
Enter percentage to compensate in relation to load when motor runs at high speed.
Change-over point is automatically calculated based on motor size.
Function:
Compensation for load dependent motor slip.
Slip compensation is calculated automatically based on rated motor speed, n
NB!
This function is only active when par. 1-00,
[0], and when par. 1-01,
Function:
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.
