Access to the individual components of the fine offset is achieved through component
specification FI (Translation Fine).

With MD18600: MM_FRAME_FINE_TRANS is used to configure the fine offset for the
following variants:
0:
The fine offset cannot be entered or programmed. G58 and G59 are not possible.
1:
Fine offset for settable frames, basic frames, programmable frames, G58 and G59 can be
entered/programmed.
Description
A fine offset changed with the HMI operation does not apply until after activation of the
corresponding frame, i.e. activation via G500, G54...G599. Once activated, a fine offset of a
frame remains active the whole time the frame is active.
The programmable frame has no fine offset. If the programmable frame is assigned a frame
with fine offset, then the total offset is established by adding the coarse and the fine offset.
When reading the programmable frame the fine offset is always zero.
