5.3 Examples of adaptive control
General procedure
The following examples use the polynomial evaluation function SYNFCT().
1. Representation of relationship between input value and output value (real-time variables
2. Definition of this relationship as polynomial with limitations
3. With position offset: Setting the MD and SD
4. Activation of the control in a synchronized action
134
in each case)
– MD36750 $MA_AA_OFF_MODE (Effect of value assignment for axial override in case
of synchronized actions)
– SD43350 $SA_AA_OFF_LIMIT (optional) (Upper limit of the offset value $AA_OFF in
case of clearance control)
Comment
; Always when the distance-to-go of the part infeed
; Equal to 0,
; Then set the axial override of the
; oscillating axis to 100% (so that the
; previous synchronized action
; is cancelled!)
If the current position of the oscillating axis in
the
Workpiece coordinate system
Equal to reversal position 1,
Then set the axial override of the
Oscillating axis to 100%
and set the axial override of the
; infeed axis to 100% (so that the
; second synchronized action once
; is cancelled!)
