FANUC Series 16/18/160/180-Model C Machining Center Operators Manual

15. COMPENSATION FUNCTION
B–62764EN/01
PROGRAMMING
334
NOTE
1 When a G28, G30, or G30.1 command specifies an axis that is not in the cutter compensation
C plane, a perpendicular vector is generated at the end point of the previous block, and the tool
does not move. In the next block, offset mode is automatically resumed (in the same way as
when two or more continuous blocks do not specify any move commands).
Example: When CCN (bit 2 of parameter No. 5003) = 1
2 When a G28, G30, or G30.1 block is specified such that the block becomes a start–up block,
a vector perpendicular to the move direction is generated at an intermediate position, then
subsequently canceled at the reference position. In the next block, an intersection vector is
generated.
Example: When CCN (bit 2 of parameter No.5003)=1
