Further settable zero offsets, G505 to G599
Command numbers G505 to G599 are available for this purpose. This enables you to create
up to 100 settable zero offsets in total, in addition to the 4 default zero offsets G54 to G57,
by using the machine data. They are stored in the zero point memory.
Deactivating a zero offset
Command G500 activates the first settable zero offset including basic offset, i.e., when zero
frame is selected as the default, the current settable zero offset is deactivated.
G53 suppresses the programmable and settable offset modally.
G153 has the same effect as G53 and also suppresses the total basic frame.
SUPA has the same effect as G153 and also suppresses the DRF offset, overlaid motions,
and external ZOs.
Note
The basic setting at program start, e.g., G54 or G500, can be set with machine data.
You will find more information on programmable zero offsets in the Frames section
"Programmable zero offset".
