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:
Applica-
tion de-
pend-
ent*
[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.
1-7* Start Adjustments
Parameters for setting special motor start features.
1-71 Start Delay
Range: Function:
0.0 s* [0.0 - 120.0 s] The function selected in par.1-80
Function at Stop is active in the delay
period.
Enter the time delay required before commencing acceleration.
1-73 Flying Start
Option: Function:
This function makes it possible to catch a motor that is spinning freely
due to a line drop-out.
When par.1-73
Flying Start is enabled, par.1-71 Start Delay has no func-
tion.
Search direction for flying start is linked to the setting in par.4-10
Motor
Speed Direction.
Clockwise [0]: Flying start search in clockwise direction. If not successful,
a DC brake is carried out.
Both Directions [2]: The flying start will first make a search in the direction
determined by the last reference (direction). If unable to find the speed,
it will search in the other direction. If not successful, a DC brake will be
