12.5.5 Example 5: Reoptimize the speed control loop to eliminate known periodic
disturbance frequencies.
This example shows how the speed controller from the part program is reoptimized without
new measurement. The objective of the reoptimization is to minimize vulnerability to known
process-related periodic disturbance frequencies. The path interpolation is not reoptimized in
this example because the optimization strategy for the position controller provides a dynamic
customization by setting an equivalent time.

; Add axis 2 because of the path inter-
polation.
; Add axis 3 because of the path inter-
polation.
; Add axis 5 because of the path inter-
polation.
; Remove the current DDS from the data
set list.
; Add DDS3 to the data set list and over-
write after optimization.
; Axis: Add parameter set 4 to the data
set list and overwrite after optimiza-
tion.
; Save the original state in a file.
; Measure axis 4 again and reoptimize,
save the boot files.
; Reoptimize axis 1 without measurement
(because of the path).
; Reoptimize axis 2 without measurement
(because of the path).
; Reoptimize axis 3 without measurement
(because of the path).
; Reoptimize axis 5 without measurement
(because of the path).
; Start the optimization by activating
the results.
; Save the optimization data in an XML
file.
; Export the speed-controlled system.
; Fetch the inertia.
; Close the optimization session.
