7 Setting the Position Detection System
(4) Select the handle mode or the JOG mode.
(5) 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 I" can be selected by setting "2" for "#2049 type
Absolute position detection method". Confirm whether the machine specifications allow the "marked
alignment method" before changing the type.
(6) Set "1" to "#0 INIT. SET" of the axis for which the zero point is to be initialized.
(7) Set the parameter "#2 ZERO".
(8) Move the axis to the marked point.
(9) Set "1" for "#1 ORIGIN" on the [ABS. POSITION SET] screen.
(10) Move the axis in the direction designated with the parameter "#2050 absdir".
The axis automatically stops when it has reached the first grid. Then the absolute position is established and the
basic machine coordinate system is automatically set.
(11) Carry out the absolute position initialization set for all the axes, and then turn the power ON again.
