P2: Positioning axes
10.6 Block change
Changing the axis state
The axis for which a block change occurred within the braking ramp can only be
programmed in the following block in the same axis state.
When the axis state changes, e.g. to
motion criterion
● a positioning axis becomes a path axis
● if the program waits for the end of the positioning movement:
● Velocity override is deactivated or activated

Comment
; Default setting is effective.
; Positioning motion from X to position 100.
; Block change criterion: "Exact stop fine"
; Block change criterion: "Braking ramp", 100% = start of
the braking ramp.
; The block is changed as soon as the X axis starts to
brake.
; Axis X does not brake at position 200, but moves further
to position 250. As soon as the axis starts to brake, the
block is changed.
; Axis X brakes and returns to position 0,
the block change is realized at position 0 and "exact stop
fine".
; Axis X traverses as path axis to position 10.
