Bit 0 (ZPR) of parameter No. 1201 is used for automatically setting the
coordinate system. When ZPR is set, the coordinate system is
automatically determined when manual reference position return is
performed.
When a, b and g are set in parameter 1250, the workpiece coordinate
system is determined so that reference point on the tool holder or the
position of the tip of the reference tool is X= a, Y = b, Z = g when
reference position return is performed. This has the same effect as
specifying the following command for reference position return:
G92Xa
YbZg;
However, when options of the workpiece coordinate system is selected,
it is not able to use.
Once the REFERENCE POSITION RETURN COMPLETION LED
lights at the completion of reference position return, the tool does not
move unless the REFERENCE POSITION RETURN switch is turned
off.
The REFERENCE POSITION RETURN COMPLETION LED is
extinguished by either of the following operations:
– Moving from the reference position.
– Entering an emergency stop state.
For the distance (Not in the deceleration condition) to return the tool to
the reference position, refer to the manual issued by the machine tool
builder.
