7.3.4 Dog-type Absolute Position Zero Point Initialization Set
Execute the dog-type reference position return with the manual reference position return mode or automatic reference
position return command (G28).
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)
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 "DOG" 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 "DOG" can be selected by setting "3" for "#2049 type Absolute position detection
method". Confirm whether the machine specifications allow the "DOG" before changing the type.
(2)
Perform manual or automatic dog type reference point return.
(3)
The absolute position will be established under the completion of the reference position return. The basic machine
coordinate system will be automatically set.
(4)
Carry out the absolute position initialization set for all the axes, and then turn the power ON again.
(Note 1) If the dog type reference position return is stopped by resetting, the previous state (OK or NG) will be
displayed for "STATE".
(Note 2) The necessary data will be saved in EEROM upon the establishment of the absolute position. The message
notifies that the data is being written in EEROM.
(Note 3) With dog-type, the reference position return can be executed again even if the "STATE" displays "OK".
