Explanation
- Compensation methods
Two methods are available to geometry compensation and wear
compensation, compensation with tool movement and compensation
with coordinate shift. Which compensation method to select can be
specified with parameters LWT (No. 5002#2) and LGT (No. 5002#4).
If, however, the tool geometry and wear compensation options are not
provided, compensation with tool movement is assumed
unconditionally.

- Compensation with tool movement
The tool path is offset by the X, Y, and Z tool offset values for the
programmed path. The tool offset distance corresponding to the
number specified by the T code is added to or subtracted from the end
position of each programmed block.
The vector with tool offset X, Y, and Z is called the offset vector.
Compensation is the same as the offset vector.
This move command block
