Back to reference point
before machining
Whether backing to machine origin
before machining is a must or not.
Yes: Required
No: Not required
Cancel REF Sign on
Estop
Whether the mark of backing to the
machine origin will be cleared or not
once E-stop occurs.
Yes: Cleared
No: Not cleared
Returning to the machine origin before machining can prevent machining offset, ensuring position
precision. It is recommended t
o set ―Yes‖ for parameter ―Cancel REF Sign on Estop‖ so that once
E-stop occurs, the mark will be cleared, and the system will remind users to back to machine origin.
If ―Back to reference point before machining‖ is set ―Yes‖ and there is no mark ―
‖ before each
axis, the machine is not allowed to move until backing to machine origin is finished. The parameter
can be set ―No‖ when returning to machine origin is impossible due to home switch error.

X direction in backing to
reference point
They set the direction of each axis in
coarse positioning stage, i.e. the
motion direction of machine tool
towards the home switch from any
point.
1: positive direction
-1: negative direction
Y direction in backing to
reference point
Z direction in backing to
reference point
A direction in backing to
reference point
Retract distance of X axis
They set the additional distance after
fine positioning of backing to the
machine origin. Positive value means
positive motion direction and negative
value negative motion direction.

In order to establish a machine coordinate system correctly during machine working period, a
machine reference point (measuring beginning) will be set within the moving range of each
coordinate axis. In machine start-up, generally returning to the reference point will be executed
automatically or manually, i.e. machine tool will return to its measuring beginning (X, Y, Z=0) to
