Description
The absolute translation component is modified by the following commands:
• TRANS
• G58
• CTRANS
• CFINE
• $P_PFRAME[X,TR]
The additive translation component is modified by the following commands:
• ATRANS
• G59
• CTRANS
• CFINE
• $P_PFRAME[X,FI]
The table below describes the effect of various program commands on the absolute and
additive offsets.
Effect of the additive/absolute offset:

Replaces the absolute translation component of the programmable zero
offset for the specified axis, but the programmed additive offset remains
valid, (in relation to the workpiece zero set with G54 to G599)
Replaces the absolute translation component of the programmable zero
offset for the specified axis, but the programmed absolute offset remains
valid
