SINAMICS G120 Control Units CU230P-2 Parameter Manual (LH9), 06/2011
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
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.
Description: Displays the parameterized total moment of inertia ((p0341 * p0342) * p1496).
Description: Sets the scaling for the acceleration pre-control of the speed/velocity controller.
Dependency: Refer to: p0341, p0342
Note: The parameter is set to 100% by the rotating measurement (refer to p1960).
The acceleration pre-control may not be used if the speed setpoint manifests significant ripple (e.g. analog setpoint)
and the rounding-off in the speed ramp-function generator is disabled.
We also recommend that the pre-control mode is not used if there is gearbox backlash.
Description: Sets the scaling for the acceleration integrator at low speeds (only for encoderless torque control).
Dependency: Refer to: p0341, p0342
