ORIGIN SELECTION
Zero offsets (G54-G59/G159)
4.
(SOFT V02.0X)
49
Only one zero offset may be active at a time; therefore, when applying
a zero offset, the previous one will be canceled. When programming
G53, the zero offset currently active will be canceled.
The function corresponding to the selected zero offset may be
programmed in any block of the program. When added to a block with
path information, the zero offset will be applied before executing the
programmed movement.
Considerations
A zero offset, by itself, does not cause any axis movement.
When homing an axis in JOG mode, the absolute zero offset for that
axis is canceled.
Properties of the functions
Functions G54, G55, G56, G57, G58, G59 and G159 are modal and
incompatible with each other and with G53 and G92.
On power-up, the CNC assumes the zero offset that was active when
the CNC was turned off. On the other hand, the zero offset is neither
affected by functions M02 and M30 nor by RESETTING the CNC.
