6.13.3 Position change
After rewriting the command position, turning the position change signal (PCHG) on causes the command
position to be changed. For automatic operation rewrite position data in the operating point table and for
incremental feed, rewrite the feed movement amount.
During linear interpolation operation, rewrite the position data in each point table of the axes in the group.
(1) To change the command position to the position which is not yet passed
(a) For automatic operation and incremental feed
An example of the position change from the command position 1 to the command position 2 is shown
below.

API LIBRARY
Use the sscChangeAutoPosition function to perform a position change for
automatic operation.
Use the sscChangeLinearPosition function to perform a position change for
linear interpolation operation.
Use the sscChangeManualPosition function to perform a position change for
incremental feed.
