4.5 Zero offset cancellation (G53)
Executing function G53 cancels the active zero offset resulting either
from a preset (G92) or from a zero offset, including the incremental
offset and the defined axis exclusion. It also cancels the zero offset
due to a probing operation.
Fixture offsets and PLC offsets are not affected by this function.
Contrary to the #MCS and #MCS ON/OFF instructions that always
execute movements referred to machine zero, function G53 allows to
execute movements referred to the fixture zero (if it is active).
Function G53 may be programmed in any block of the program. When
added to a block with path information, the offset or preset is canceled
before executing the programmed movement.
Considerations
Function G53, by itself, does not cause any axis movement.
Properties of the function
Function G53 is modal and incompatible with function G92, zero
offsets and probing.
