SINAMICS G120 CU240B/E-2 Control Units List Manual (LH11), 01/2013
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 sig-
nal 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
Description: Enables the droop to be applied to the speed/velocity setpoint.
Dependency: Refer to: p1486, p1487, 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.
Description: Displays the parameterized total moment of inertia ((p0341 * p0342) * p1496).
