(5) Zero point initialization for dog type absolute position detection
By executing dog type zero point return with the manual zero point return mode or automatic zero
point return command (G28), the zero point will be initialized. The execution stage of the
initialization will be showed in the "STATE" column of the [ABS. POSITION SET] screen. The "#0
INIT. SET", "#1 ORIGIN" and "#2 ZERO" settings are invalid during dog type absolute position
detection.
[Operation procedure/operation]
Operation procedure STATE display
1. Select the [ABS. POSITION SET] screen.
2. Confirm that the axis to be zero point initialized is a "dog
type" axis. (See "TYPE" on the [ABS. POSITION SET] screen.)
• NG if the absolute position is
lost.
• OK if the absolute position is
established.
3. Perform manual or automatic dog type zero point return.
ZP-RTN
4. The basic machine coordinate system will be established
when the zero point is reached. The absolute position is
established at this stage, and the zero point initialization is
completed.
COMPLETE
5. Output the parameters after zero point initialization is
completed for all axes.
(Note 1) If the dog type zero point return is stopped by resetting, the previous state (OK or NG) will
display in the "STATE" column.
(Note 2) After the absolute position has been established, save the necessary data in the memory.
(Note 3) With dog type zero point return, zero point return can be executed again even if the
"STATE" is OK .
