Description
! Caution
Unless G53 is executed, the origin of the workpiece coordinate system is deter-
mined by the system parameter ("workpiece origin offset" of the coordinate
parameter) when executed from the top of the program.

Data
This function changes the present value of the specified reference coordinate
system to a specified value. For the absolute encoder axis, if the servo lock is
executed after the servo free is executed, the position will be preset to the abso-
lute position registered in the absolute encoder.
The present position presetting for the absolute encoder axis applies only to the
present position registered in the MC Unit. The present position registered in the
absolute encoder will not be preset. Therefore, the position will be automatically
updated to the present position registered in the absolute encoder when the next
time the servo lock is executed.
