5.5 Preset offset (PRESETON)
Function
For special applications, it may be necessary to assign an already referenced machine axis
a new actual value using
PRESETON. This corresponds to a zero offset in the machine
coordinate system.
CAUTION
After
PRESETON, the machine axis is in the "non-referenced" status. We therefore
recommend that the function is only used for machine axes that do not require a reference
point. In order to restore the original machine coordinate system, the machine axis must be
re-referenced, e.g. using G74 (reference point approach).

Syntax
PRESETON(<axis>, <value>, ...)
Meaning
PRESETON
Preset actual value memory
<axis>

Note
Setting actual values via synchronized actions should only be implemented with the keyword
WHEN or EVERY.
