6.17.5 Path Resulting After Handle Interruption

(1) For incremental (G91) mode
The locus deviates from the program path by the distance of interruption. (See the figure below.)
Program path
(G91 X_ Y_;)
Distance of interruption by manual handle
(2) For absolute (G90) mode
If program absolute position update by the distance of handle interruption is disabled, the locus deviates from the
program path by the distance of interruption.
If this update is enabled, the locus returns to the program path during processing of the following command:
For single block running - Return command is issued in the block next to the one for which the interruption has been
completed.
For continuous running - Return command is issued in the third block, if the block for which the interruption has
been completed is the first block.
(Note) Both POSITION and MACHINE display include the distance of handle interruption.
For automatic handle interruption, select whether absolute mode is updated or not, as follows:
(a) Using machine parameters, set whether the manual absolute changeover switch or parameters are used.
(b) If the parameters are used, set whether or not absolute position data is updated for each axis, by using
machine parameters other than those in item.
(c) If the manual absolute changeover switch is used, use the machine operation panel switch for selection.
