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 optimum U/f characteris-
tic. 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
1-62 Slip Compensation
Range: Function:
0 %* [-500 - 500 %] Enter the % value for slip compensation, to compensate for tolerances
in the value of n
M,N
. Slip compensation is calculated automatically, i.e.
on the basis of the rated motor speed n
M,N
.
1-63 Slip Compensation Time Constant
Range: Function:
0.10 s* [0.05 - 5.00 s] Enter the slip compensation reaction speed. A high value results in slow
reaction, and a low value results in quick reaction. If low-frequency res-
onance problems arise, use a longer time setting.
1-64 Resonance Dampening
Range: Function:
100 %* [0 - 500 %] Enter the resonance dampening value. Set par.1-64
Resonance Damp-
ening and par.1-65 Resonance Dampening Time Constant to help elimi-
nate high-frequency resonance problems. To reduce resonance oscilla-
tion, increase the value of par.1-64
Resonance Dampening.
1-65 Resonance Dampening Time Constant
Range: Function:
5 ms* [5 - 50 ms] Set par.1-64
Resonance Dampening and par.1-65 Resonance Dampening
Time Constant to help eliminate high-frequency resonance problems.
Enter the time constant that provides the best dampening.
