7. COORDINATE SYSTEMS
NC FUNCTION
105
The workpiece coordinate system with its zero position away by the
workpiece zero offset amount from the machine coordinate system zero
position is set by returning the tool to the reference point by a manual
operation. Also, when the absolute position detector is provided, the
workpiece coordinate system is automatically set by reading the machine
coordinate value from the detector when power on without performing
manual reference point return operation. The set workpiece coordinate
may shift by any of the following commands or operation:
D When manual interruption is performed with the manual absolute
signal off
D When the travel command is performed by the machine lock
D When axis travel is performed by the handle interrupt or auto/manual
simultaneous operation
D When operation is performed by mirror image
D When the setting of local coordinate system is performed by the G52
or change of workpiece coordinate system is performed by the G82
The workpiece coordinate system shifted by the above operation can be
preset by the G code instruction or MDI operation the same as
conventional manual reference point return.
The workpiece coordinate system can be preset by commanding the
G92.1 0 ;
0 : The axis address to be preset the workpiece coordinate system
Uncommanded axis is not preset.

The workpiece coordinate system can be preset by the MDI operation
with soft keys.
