C70 Setup Manual
7.3 Adjustment in Absolute Position Detection System
131
(Note 1) When changing only the basic machine coordinate zero point, carry out steps (6) and (7) above and then turn
the power OFF and ON.
(Note 2) At the step (9), if the first grid point is on the grid mask ("#2028 grmask"), the axis will stop at the next grid
point.
Note that the zero point shift ("#2027 G28sft") is invalid.
(Note 3) If no movement takes place in step (8), recheck the "#2050 absdir" direction.
When this parameter is set to "0", the axis will move only in the forward direction. When set to "1", only in the
reverse direction.
7.3.3.4 Marked Point Alignment Method II
In a similar way to the "Marked Point Alignment Method I", this is a method to align to the marked point (matchmark or
marking line) on the machine. However, the grid return will not be performed and the basic point is set as the absolute
position zero point. Use GOT project controlled by sequence programs, switches on the machine operation panel,
manual handle, and the [ABS. POSITION SET] screen in the CNC monitor on GOT for the absolute position zero point
initialization set. The GOT project and panel switches are made by the machine tool builder.
(1)
Display [ABS SERVO MONITOR] screen from [TOOL PARAM].
(2)
Select the handle mode or the JOG mode.
(3)
Select [ALARM/DIAGN] ---> [MENU (MENU 5)] ---> [ABS SERVO MONITOR] in the CNC monitor on GOT. Scroll
the page to display the [ABS. POSITION SET] screen.
Check that the NO-STOPPER is applied for the axis for which the absolute position zero point is to be initialized.
(Note)
The type of absolute position zero point initialization set is decided by the machine and axes
specifications, although "marked alignment method II" can be selected by setting "4" for "#2049 type
Absolute position detection method". Confirm whether the machine specifications allow the "marked
alignment method II" before changing the type.
