The auxiliary zero position can be set in two ways:
1) Coordinate entering;
2) Zero clearing in place.
4.1 Entering the ZER Zero Position Directly
Without moving the machine, follow the dimensions on the user
processing drawing to directly preset the user coordinate zero point, In this
way, the user coordinate zero point can be set precisely and quickly.
In the user coordinate system (ZER coordinate system), enter the
coordinate of an auxiliary zero position at the absolute coordinate zero
position, and the coordinate position of absolute coordinate zero (point 0) in
the auxiliary zero position coordinate is displayed. Viewed in the relative
coordinate system, point 0 is at (25,-20) of point A, (-30,-25) of point B,
(-30,30) of point C, and (25,20) of point D, exactly the opposite numbers of
position of each point in the absolute coordinate system. If you enter the
relative zero position at a point outside of the absolute coordinate system,
the position of this point in this user coordinate is displayed. If you enter the
auxiliary zero position of point B in the user coordinate at point A, the
displayed value of B is (-55,-5). Therefore, when a value is preset in the ZER
coordinate system, a minus is added to get the opposite number
automatically. Hence, the coordinate value of the processed work-piece can
be directly used for entry.
Operating steps
：
1. In the absolute coordinate system
(ALE), move the machine and aim
the tool at the center point 0 as shown in Figure 3.1.
Press keys X
0
and Y
0
for zero clearing for data on axis X and axis Y
and to determine the zero position of the absolute coordinate.
2. Press the “ZER” function key to
enter the user coordinate system.
Enter the ZER 1 coordinate, set
the position of point A, and enter its
coordinate value (-25,20). If you
find that the entry is wrong,
press the axis key to cancel the entry.
