(7) Procedures This shows the procedures to establish the coordinate system by zero point
initialization. The contents differ depending on the type of zero point initialisation.
(8) Initialization message This displays a message with the background yellow if an illegal value has been set
for the zero point initialization. Refer to the section "10. Appendix" for details.
(Note) [Type of zero point initialization] indicates the progress state of zero point initialization as shown below.
1.Dogless-type absolute position detection system
Machine end stopper method (manual initialization)
Order Display Details of progress
1 Illegality While the absolute position is lost.
2 Stopper From when the menu "Abs pos set" is pressed
to when the axis pushes against the machine end stopper.
3 Release From when the axis pushes against the machine end stopper
to when axis starts to move in the counter direction.
4 Ret. Ref. P. From when the axis moves in the counter direction
to when it reaches the grid point immediately before the stopper.
5 Complete The axis has reached the grid point immediately before the stopper.
The absolute position has been established.
2. Dogless-type absolute position detection system
Machine end stopper method (automatic initialization)
Order Display Details of progress
1 Illegality While the absolute position is lost.
2 Jog Start From when the menu "Abs pos set" is pressed
to when a value is set in "Zero-P".
3 Stopper1 From when JOG operation starts
to when the axis pushes against the machine end stopper.
4 Zero-P. Rel. From when the axis pushes against the machine end stopper
to when axis reaches the approach point.
5 Stopper2 From when the axis reaches the grid point immediately before the stopper
to when it pushes against the machine end stopper.
6 Ret. Ref. P. From when the axis pushes against the machine end stopper second time
to when axis reaches the grid point immediately before the stopper.
7 Complete The axis has reached the grid point immediately before the stopper.
The absolute position has been established.
3. Dogless-type absolute position detection system
Marked point alignment method
Order Display Details of progress
1 Illegality While the absolute position is lost.
2 Origin Set From when the menu "Abs pos set" is pressed
to when "1" is set in "Origin-P".
3 Ret. Ref. P. While moving in the direction designated with the absolute position parameter #2050.
4 Complete The axis has reached the grid point immediately before the marked point.
The absolute position has been established.
4. Dogless-type absolute position detection system
