7. POSITIONING CONTROL
The operation that takes place on execution of a skip designated during constant speed control,
when an axis for which "degree" is designated as the unit and which has no stroke range is in-
cluded, is described here. If, under these conditions, there is an ABS instruction following the
skip, the final positioning point and the travel distance in the program as a whole will be the same
ragardless of whether the skip is executed or not. Examples are presented below.
(1) When all the instructions after the skip are INC instructions:

(2) When the instruction immediately following the skip is an ABS instruction

(3) When the instruction immediately following the skip is an INC instruction and there is an ABS
