p1488[0...n]
Droop input source / Droop input,source
VECTOR (n/M)
Can be changed: U, T
Data type: Integer16
P-Group: Closed-loop control
Not for motor type: REL

Dependency:
Refer to: p1489, r1490, p1492
p1489[0...n]
Droop feedback scaling / Droop scaling
VECTOR (n/M)
Can be changed: U, T
Data type: Floating Point
P-Group: Closed-loop control
Not for motor type: REL
Min
0.000
Description:
Sets the scaling for the droop feedback
Dependency:
Refer to: 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 (n/M)
Can be changed: -
Data type: Floating Point
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: p1488, p1489, p1492
p1492[0...n]
BI: Droop feedback enable / Enables droop
VECTOR (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: p1488, p1489, r1490
Note:
Even when not enabled, the droop speed is calculated but not subtracted from the setpoint speed. This makes it
possible to subtract the result of this calculation from the speed of another drive.
