List of parameters
p1486[0...n] CI: Droop compensation torque / Droop M_comp
Access level: 3
Can be changed: T
Units group: -
Min
-
Description: Sets the signal source for the compensation torque to be output within the droop calculation.
This parameter should be interconnected with the torque setpoint of the drive (corresponding to the selection
p1488), with which load equalization should be performed.
p1487[0...n] Droop compensation torque scaling / Droop M_comp scal
Access level: 3
Can be changed: U, T
Units group: -
Min
-2000.0 [%]
Description: Sets the scaling for the compensation torque within the droop calculation.
p1488[0...n] Droop input source / Droop input source
Access level: 3
Can be changed: U, T
Units group: -
Min
0
Description: Sets the source for droop feedback.
With increasing torque, the speed setpoint is reduced (enabled using p1492), so that for mechanically coupled
drives a load equalization (load compensation) is obtained.
A load difference compensation is also possible, if p1486 is interconnected with the torque setpoint of the other
drive.
Value: 0:

3:
Dependency: Refer to: p1486, p1487, p1489, r1490, p1492
Caution: For active acceleration precontrol of the speed controller (refer to p1496), it is not recommended that p1488 is set
to 1, as this could result in positive coupling effects. Instead of this, as source of the droop feedback, the output sig-
nal of the speed controller should be used, which generally sets the load torque.
p1489[0...n] Droop feedback scaling / Droop scaling
Access level: 3
Can be changed: U, T
Units group: -
Min
0.000
Description: Sets the scaling for the droop feedback
Dependency: Refer to: p1486, p1487, p1488, r1490, p1492
Note: Example:
A value of 0.05 means that for a torque equal to the rated motor torque, the rated motor speed is reduced by 5 %.
