p1488[0...n] Droop input source / Droop input source
VECTOR_G (n/M) Can be changed: U, T
Data type: Integer16
P-Group: Closed-loop control
Not for motor type: REL
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 signal
of the speed controller should be used, which generally sets the load torque.
p1489[0...n] Droop feedback scaling / Droop scal
VECTOR_G (n/M) Can be changed: U, T
Data type: FloatingPoint32
P-Group: Closed-loop control
Not for motor type: REL
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 %.
r1490 CO: Droop feedback speed reduction / Droop n_reduction
VECTOR_G (n/M) Can be changed: -
Data type: FloatingPoint32
P-Group: Closed-loop control
Not for motor type: REL
Min
- [rpm]
Description: Displays the output signal of the droop calculation. The droop feedback result is subtracted from the speed setpoint
when activated (p1492).
Dependency: Refer to: p1486, p1487, p1488, p1489, p1492
p1492[0...n] BI: Droop feedback enable / Droop enable
VECTOR_G (n/M) Can be changed: U, T
Data type: Unsigned32 / Binary
P-Group: Closed-loop control
Not for motor type: REL
Min
-
Description: Enables the droop to be applied to the speed/velocity setpoint.
Dependency: Refer to: p1486, p1487, p1488, p1489, r1490
