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:

	KP
	P550
	P225
	Threshold 1	Threshold 2	Input
	P556	P559	selected in P553
Adaptation of the integration time:
	Tn
	P551
	P226
	Threshold 1	Threshold 2	Input
	P557	P560	selected in P554
Adaptation of the droop:
	St
	P552
	P227
	Threshold 1	Threshold 2	Input
	P558	P561	selected in P555
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.
