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.
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).
