Comment
;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 axis X starts to brake.
;Axis X no longer brakes at position 200, but rather contin-
ues to traverse to position 250. As soon as the axis starts
to brake, the block changes.
;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.
Comment
;End-of-motion criterion: "Exact stop fine"
;The technology cycle block change is realized if the X axis
has reached position 100 and "exact stop fine" is reached.
;Activate block change criterion "braking ramp",
100% = start of the braking ramp.
;Technology cycle block is changed as soon as axis X starts
to brake.
;X axis does not brake at position 200, but rather continues
to traverse to position 250. As soon as the X axis starts to
brake, the block change takes place in the technology cycle.
;X axis brakes and returns to position 0,
the block change is realized at position 0 and "exact stop
fine".
Comment
;Default setting 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.
;Tolerance window: 1 = setpoint position, tolerance = 0.5
;The block is changed as soon as axis X starts to brake.
;Axis X no longer brakes at position 200, but rather contin-
ues to traverse to position 250. As soon as the axis starts
to brake, the block changes.
