If "#2059 zerbas" is "0" (absolute position origin point = mechanical basic position), axis will stop automatically at this
point without moving in the opposite direction and "Complete" appears at [State] and "0.000" at [Machine end].
(Note 1) To change just the basic machine coordinate zero point, set "#0 Absolute posn set" and "#2 Zero-P", and then
turn the power OFF and ON.
(Note 2) If pressing against the machine end is attempted without passing the grip point once after turning the power
ON, the operation message "Not passed on grid" will appear. Return to a point before the last grid, and then
repeat from step of pressing against the machine end stopper.
(Note 3) If the first grid point is covered by the grid mask (#2028 grmask) as a result of return to the electric basic
position, the axis stops at the next grid point.
Note that zero-point shift amount (#2027 G28sft) is invalid.
