(3) To the movement of the next block for the vertical direction (Parameter
No.5003#1(SUV)=1)
As shown in the following figures, when G41.2, G42.2, or G40 is specified, a
block is inserted which moves the tool perpendicularly to the movement
direction specified in the next block by the distance of the tool radius.

Note
If the movement of the next block for the vertical direction (parameter
SUV(No.5003#1)=1), the following conditions must be satisfied when tool
side compensation is started up or canceled :
1 The block containing G40, G41.2, or G42.2 must be executed in the G00
or G01 mode.
2 The block containing G40, G41.2, or G42.2 must have no move
command.
3 The block after the block containing G41.2 or G42.2 must contain a G00,
G01, G02, or G03 move command.
