Control with INC-3 (incremental method)
(1) Positioning control from the current stop position to the position which is the
resultant of the designated travel directions and travel values of the respective
axes.
(2) The travel direction of each axis is designated by the sign of the travel value, as
follows:
•
Positive travel value .............forward direction (increased address)
•
Negative travel value............reverse direction (decreased address)
