Combination with backward motion
Backward motion on the path during delete distance to go
The short cut motion is calculated online by the PLC signal and not saved in the ISO program. For this reason, the short cut path can not move backwards.
If the user (PLC) requests backward motion while travelling on a short cut (N20'), the motion is interrupted (same as for FEEDHOLD) and a warning is output. As soon as the backward motion signal is reset, motion on the short cut is resumed.
If the backward signal is set after reaching the target position of the short cut, the backward motion is executed on the original contour (N20) which was programmed in the ISO program and not on the short cut.
Notice
The short cut executed with "delete distance to go" in not considered for backward motion. The original contour from the ISO program is always considered for backward motion.
Delete distance to go during backward motion
If the motion is already in a backward direction, the request for "delete distance to go" is only executed in the backward direction.
