Home Setup
Home Function
“Home” is the machine origin. “Go to home” refers to moving all axes back to the machine
origin. Home position depends on home sensor. Normally there are 3 sensors on a 3-axis
machine. “Go to home” operation sets up the relationship between the machine and the
working co-ordinates. Many system function applications rely on this operation, such as stop
point save, power off reboot and so on.
It is good practice to home a machine after switching the power on.
If you enter the menu by pressing ,"MENU" please press "STOP/CANCEL"to exit and return to MANL
as no changes are required here under normal use.
Home Operating
When the power is turned on, “Go to Home?” appears on the screen: this is a question
which will need to be answered by the operator:
Pressing "ORIGIN/OK"means “Yes”- the Z axis moves first; when the Z axis arrives at its home
position, the X and Y will also move to the home position.
Pressing "RUN/PAUSE/DELETE" means “No”- the 3 axes do NOT move to their home positions.
Pressing any other KEY- Only the Z axis moves to home position; X and Y do NOT go home.
When the machine is moving to the home position, you can press the KEY to stop
“Homing”. The controller is now in Manual Mode. Pressing "HOME/9" will move the machine to
home when in manual mode.
Pressing "XY-0/4" will zero X & Y. Pressing "Z-0/8" will zero Z creates an origin point which
the pendant controller uses when running a CNC program.
Pressing will move the machine to the origin point for the current working
coordinate when in manual mode.
1X 0.000, 1Y 0.000, 1Z 0.000
================================================== ======
According to this manual. Origin and Home should be the same which is XYZ0.
I have set the new XY zero point by pressing "XY-0/4".
After reset new XY zero point when I press "ORIGIN/OK" the spindle goes to new XYzero point. But when I press "HOME" key spindle goes past the point till hit the limit sensor.
Is this normal ?
