(1) The current position in the work coordinate system is changed to the specified
coordinates value, a new work coordinates is set. The work coordinates system is
set in the specified position (offset from the current position).
By making coordinates system setting, the virtual mechanical coordinates is set
and the work coordinate systems 1 to 6 travel in parallel.

(2) Positioning data can be set by direct setting (numerical value) and indirect setting
(variable : #
(3) By executing G92 in the constant-speed positioning command (e.g. G01),
deceleration stop is made once. When G92 is executed in the single block mode,
making a single block start twice in the same block shifts execution to the next
block.
POINT
If the current value is changed in G92, the current value data restored after a power
failure is based on the status prior to execution of G92.
The mechanical coordinates (virtual mechanical coordinates) is set
simulatively.
Setting the virtual mechanical coordinate system also changes the work
coordinates systems 1 to 6.
