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: 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
Access level: 3
Can be changed: -
Units group: 3_1
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 / Droop enable
Access level: 3
Can be changed: U, T
Units group: -
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.
r1493 CO: Moment of inertia, total / M_inertia total
Access level: 3
Can be changed: -
Units group: 25_1
Min
- [kgm²]
Description: Displays the parameterized total moment of inertia ((p0341 * p0342) * p1496).
