unchanged, then the tool stops at the first grid point (electric grid
point).
(6) Upon confirmation that the current position is in the in-position
area, the reference position return end signal (ZP1, ZP2, ZP3,0)
and the reference position establishment signal (ZRF1, ZRF2,
ZRF3,0) turn to "1".
If the feed axis direction selection signal (+J1, -J1, +J2, -J2,0) turns to
"0" between step (2) and (5) , the tool is stopped at once, and reference
position return is assumed to be canceled. If the signal turn to "1" again,
operation resumes from step (3) (rapid traverse).
The timing charts for the basic procedures are given below.
