14 Setting the Position Detection System
*2 The operation order is slightly different when "#2059 zerbas = 1 (grid point just before stopper)" is set. Set the
procedure (6) "Zero-P" after "Complete" is displayed on "State" of the procedure (10).

- (7), (9) and (10) in this diagram correspond to the operation procedure.
- Select either one of "#2 Zero-P" with the parameter.
(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 aligning axis on the marked point 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 aligning the axis on the marked point.
(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.
(Note 4) Reconfirm the "absdir" setting if the machine does not move in the direction of "#2050 absdir". The machine
will move only in the positive direction when set to "0", and the negative direction when set to "1".
