6 POSITIONING CONTROL
Control using INC-3 (Incremental data method)
(1) Positioning control from the current stop address to the position which combined
travel direction and travel value specified with each axis is executed.
(2) The travel direction for each axis is set by the sign (+/ -) of the travel value for
each axis, as follows:
• Positive travel value .............Positioning control to forward direction
• Negative travel value............Positioning control to reverse direction
