8.5.1 Optimization
parameters
In addition to the standard structure (which corresponds to the previous COMPAX
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:
No.

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"
The structure switch measuring (P59) permits the following settings:
No.

Sensitive stiffness (P23)
Larger setting range for P23
+16
P59
Sensitive D section (P56)
Larger setting range for P56
+65536
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.
