	0.00 Automatic switchover from PI to P controller deactivated.
(G152)	> 0.00 Depending on the actual speed (K0166), the PI controller
		switches over to a P controller if the speed drops below the
		threshold set in parameter P222. The integrator is not switched
		in again (with value of 0) until the actual speed is > P222 +
		P221.
		This function allows the drive to be stopped without overshoot
		using a zero setpoint with the controllers enabled.
		This function is active only if the binector selected in P698 is in
		the log. "1" state.

Setting values for speed controller

P223	Control word for speed controller precontrol
*	0	Speed controller precontrol disabled
FDS
	1	Speed controller precontrol acts as torque setpoint (is added to
(G152)
		n controller output)

P224	Control word for speed controller I component
*	0	Set controller I component to 0 (i.e. to achieve a pure P
FDS
		controller)
(G152)
	1	Controller I component is active
		The I component is stopped when a torque or current limit is
		reached

2Controller I component is active

The I component is stopped when a torque limit is reached

3Controller I component is active

The I component is stopped only when ±199.99% is reached

P225	Speed controller P gain
FDS	See also setting values for "Speed controller adaptation" function (P550 to
	P559).
(G151)	This parameter is set automatically during the speed controller optimization
	run (P051=26).
P226	Speed controller reset time
FDS	This parameter is set automatically during the speed controller optimization
(G151)
	run (P051=26).

Speed controller droop

Function: A parameterizable feedback loop can be connected in parallel to the I and P components of the speed controller (acts on summation point of setpoint and actual value).

P227	Speed controller droop	0.0 to 10.0	Ind: 4	P052	= 3
	A 10% speed droop setting causes a 10% deviation in the speed from the	[%]	FS=0.0	P051	= 40
FDS		0.1%	Type: O2	Online
	setpoint at a 100% controller output (100% torque or armature current
(G151)	setpoint) ("softening" of closed-loop control).
	See also P562, P563, P630 and P684
P228	Filter time for speed setpoint	0 to 10000	Ind: 4	P052	= 3
	Filtering of setpoint by means of a PT1 element.	[ms]	FS=0	P051	= 40
FDS		1ms	Type: O2	Online
	This parameter is automatically set to the same value as the speed
(G152)	controller reset time during the speed controller optimization run (P051=26).
	It may be useful to parameterize lower values when the ramp-function
	generator is in use.
