further parameters for the speed controller P200 - P236
Speed controller adaptation
The parameters of the speed controller (Kp, Tn, droop) can be altered as a function of any connector to adapt the speed controller
optimally to a changing controlled system.
The diagrams below show the active P gain, the active Integration time and the active droop depending on the value of the set connector.
Adaptation of the P gain:
Adaptation of the integration time:
Adaptation of the droop:
For parameter pairs P225/P550, P226/P551 and P227/P552 all values can be set completely mutually independently, e.g., P550 does not
have to be greater than P225. The above diagrams show only the effect of the individual parameters.
Threshold 1 must always be set smaller than threshold 2, otherwise the fault message F058 is activated.
