(b) Marked point alignment method
The handle or jog is operated to align the axis with the basic point of the machine.
Before performing zero-point initialization, specify the following parameter of the [ABS. POSI
PARAM] screen (for details, see Alarm/Parameter Manual):
#2050 absdir
[Operation procedure]
Operation procedure STATE display
1. Select the "ABS. POSITION SET" screen.
2. Select the handle mode, handle axis or jog mode.
3. Ensure that the origin point alignment method is applied for
the axis for which zero-point initialization is to be performed.
("TYPE" of [ABS. POSITION SET] screen indicates
NO-STOPPER . )
• NG if the absolute position is
lost.
• OK if the absolute position
has been established.
4. Specify "1" to "#0 INIT. SET" for the axis for which zero-point
initialization is to be performed.
5. Specify data for "#2 ZERO".
6. Move the axis to the machine basic position and align it with
the basic point.
7. Specify "1" to "#1 ORIGIN".
ORIGIN SET
8. The machine will move in the direction specified with [ABS.
POSI PARAM] "#2050 absdir".
ORIG-RTN
9. The axis automatically stops at the first grid point.
• The basic machine coordinate system is automatically
set.
This sets up the absolute position.
10. This completes zero-point initialization.
After completion of zero-point initialization for all axes, turn
power OFF and ON again.
OK
11. Output parameter tape.
To change just the basic machine coordinate zero point, perform steps 4 and 5 above, and then turn the
power OFF and ON.
