13. Program Support Functions
(7) A miscellaneous function issued in the same block as the block with the movement command
is output before the movement and starts the movement. During movement, operation will not
stop at the operating start point. However, at the end point of the block, the completion of all
the miscellaneous functions is checked first, and then the execution of the next block is
started.
(8) G117 should be issued in the sequence of operating start points. Program error (P33) occurs if
the sequence of the operating start point is the reverse of the movements.
When operating start points coincide, the miscellaneous functions are output in the sequence
in which they were issued.
(9) When an operating start point cannot be determined by the next block movement, the next
operation is performed by the parameter.

Precautions
(1) Command G117 in order of the operation start points. If the operation start point order is the
opposite of the movement, a program error (P33) will occur.
13.16 Miscellaneous function output during axis movement
G17 First block
Program error P33 occurs before movement
The functions are output when the next block
movement is completed.
