5.7.3.2 Optimise speed controller
The speed controller is in the form of a PID controller with an additional differential speed-
setpoint gain. For optimum behaviour, the PID speed controller has to be optimised and
the overall mass inertia of the drive train has to be determined.
 In the Lenze setting, the configuration of the speed controller provides robustness and
moderate dynamics.
Speed controller gain Vp
Gain Vp (C00070/2
) of the speed controller is specified in a scaled representation which
permits similar parameter setting that is almost independent of the power of the motor or
the inverter:
If the rated data of the motor and the mass inertia of the drive system are known, we
recommend the following setting:
