8.5.1 Optimization parameters

Structure	In addition to the standard structure (which corresponds to the previous COMPAX
variants:	control structure), you can select from 3 structure variants.
	These include, in addition to a specific control structure, pre-defined settings for
	specific optimizing parameters. By selecting the individual structures in the
	ParameterEditor, the following parameters can be set:

Unit	hardware
Connector	assignment / cable
data

Structure and parameter settings using the ServoManager:

No.	Meaning	Standard	Variant 1	Variant 2	Variant 3
P59	Structure switch measuring	0	4	3	8
P56	D section rpm controller (%)	0	40	40	40
P57	Filter acceleration (%)	100	175	350	100
P58	Lag rapid rpm signal (%)	100	0	0	100
P50	Monitor	100	101	101	100
		(switched off)	(switched on)	(switched on)	(switched off)
P151	Monitor speed (%)	30	30	30	30
P27	Moment of inertia (%)	100	100	85	100
P69	Return pre-control (%)	0	100	100	100
P70	Current pre-control value	0	100	100	100
	(%)

Standard: Previous COMPAX control structure; use this structure if you already have optimized parameter sets.

Variant 1: Structure switch: Variant 1 for resolver

Variant 2: Structure switch: Variant 2 for SinCos

Variant 3: Structure switch: Variant 3 "Rapid rpm controller"

P59: Structure switch measuring

P23: stiffness of drive

Increase stiffness

Reduce stiffness

The structure switch measuring (P59) permits the following settings:

No.	Meaning	Settings
P59	Structure switch measuring	0: Standard
		4: Variant 1 (for resolver)
		3: Variant 2 (for SinCos )
		8: Variant 3 (rapid rpm controller)
	Sensitive stiffness (P23)	+16
	Larger setting range for P23
	Sensitive D section (P56)	+65536
	Larger setting range for P56	The D section is reduced by 1/256.

By selecting a structure variant with the structure switch P59, no further parameters are influenced.

Only by selecting a variant through ServoManager (menu parameters: controller structure / monitor) can complete parameter sets (as described above) be set.

The stiffness is proportional to the controller speed.

Nominal value: 100% Range: 10%...5000%

Control is faster. The control circuit starts from a critical value. Set the stiffness so that sufficient safety distance from the critical value is ensured.

Control is slower. This increases lag error. Current limitation is reached later.
