Programmable work offset (G58, G59)

The G58 and G59 functions can be used to substitute translation components of
the programmable work offset (TRANS/ATRANS) (Page 310) with specific axes:
● G58: Absolute translation component (coarse offset)
● G59: Additive translation component (fine offset)
Requirements
The G58 and G59 functions can only be used if fine offset has been configured
(MD24000 $MC_FRAME_ADD_COMPONENTS = 1).
Syntax
G58 <axis_1><value_1> ... <axis_3><value_3>

G58 replaces the absolute translation component of the programmable work offset
for the specified axis, but the programmed additive offset remains valid. The ref‐
erence is provided by the last settable work offset called (G54 ... G57, G505 ...
G599).
