Droop
For mechanically coupled drives, there is the risk that the drives oppose one another: Small
deviations in the speed setpoint or actual value of the coupled drives can mean that the drives
are operated with significantly different torques.

Encoderless speed control
Description
Moment of inertia ratio, total to motor (factory setting: 1.0)
Acceleration precontrol scaling (factory setting: 0 %)
For the rotating measurement of the motor data identification the inverter sets the pa‐
rameters to 100 %.
Speed controller speed actual value smoothing time (without encoder) (factory setting:
10 ms)
Speed controller operation without encoder P gain (factory setting: 0.3)
Speed controller operation without encoder integral action time (factory setting: 20 ms)
