Machine coordinate system is a coordinate system set with a zero point
proper to the machine system.
A coordinate system in which the reference position becomes the
parameter-preset (No. 1240) coordinate value when manual reference
position return is performed, is set. With G53 command, the machine
coordinate system is selected and the axis can be moved at rapid traverse
to the position expressed by the machine coordinates.
1240
Coordinate value of the reference position on each axis in the machine
coordinate system
NOTE
After setting this parameter, turn the power off then on again
so that the setting will take effect.
[Data type] Two–word axis
Increment system IS–A IS–B IS–C Unit
Metric machine 0.01 0.001 0.0001 mm
Inch machine 0.001 0.0001 0.00001 inch
Rotation axis 0.01 0.001 0.0001 deg
[Valid data range] –99999999 to 99999999
Set the coordinate values of the reference positions in the machine
coordinate system.
WARNING
Since the machine coordinate system must be set before
the G53 command is specified, at least one manual
reference position return or automatic reference position
return by the G28 command must be performed after the
power is turned on. This is not necessary when an
absolute–position detector is attached.
