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.
This function enables the inter–rapid traverse block overlap function
between machine coordinate system select command (G53) and
positioning (rapid traverse) command (G00) blocks and allows the next
rapid traverse command (G00) to be executed at the end of the machine
coordinate system select command (G53) without decelerating to a stop.
This way, high–speed positioning becomes possible even when the
machine coordinate system select command (G53) is used.
Specifying P1 in the G53 bock enables the high–speed G53 function.

NOTE
After setting this parameter, turn the power off then on again
so that the setting will take effect.
