Marked Aligment Method I - Mitsubishi Electric M700VS Series Setup Manual

(4) Dog method
This method requires a dog sensor.
Move the table until the dog is kicked, and the first grid point after the dog OFF is determined as the basic position.
The parameters for the approach speed and grid mask amount etc. need to be adjusted.

7.1.1 Marked Aligment Method I

(1) Select [Param] -> [Abs.Posit.Param.] in the maintenance screen.
Set the following parameters in the "Abs.Posit.Param." screen.
#2049 type (absolute position detection type)
#2050 absdir (basic Z - direction)
#2059 zerbas (zero point parameter)
(2) Turn the power OFF and ON.
(3) Select [Mainte] -> [To abs pos]. The absolute position setting screen will appear.
(4) Select [Axis select]. Enter the axis name (the name set in "#1022 axname2 (2nd axis name), and hold down INPUT
key.
(5) Select HANDLE (handle axis) or "JOG" mode.
(6) Set "1" to "#0 Absolute posn set".
(7) Enter an arbitrary value to "#2 Zero-P".
(8) Move the axis toward the mechanical basic position and align it to the marked point. (a in the diagram)
(9) Set "1" to "#1 Origin-P".
(10) Move the axis in the direction designated with the parameter "#2050 absdir".
(11) The axis reached the first grid point. (c in the diagram)
When the absolute position is established, [Complete] will appear in [State].
Select [Next axis] menu, and perform the absolute position initial set up for all axes.
(12) Turn the power OFF and ON.

Zero point parameter
"#2037 G53ofs"
(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".
