2.2 List of parameters
Description: Sets the scaling for the compensation torque within the droop calculation.
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: Droop feedback not connected
1: Droop from torque setpoint
2: Droop from speed controller output
3: Droop from integral output speed controller
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.
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 %.
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
