5.5 OPTIONAL BLOCK SKIP/ADDITION OF OPTIONAL
BLOCK SKIP
Overview
When a slash followed by a number (/n, where n = 1 to 9) is specified
at the head of a block, and optional block skip signals BDT1 to BDT9
are set to 1 during automatic operation, the information contained in
the block for which /n, corresponding to signal BDTn, is specified is
ignored (from /n to the end of the block).
(Example) /2 N123 X100.0 Y200.0 ;
Input signal Code specified at the head of a block

/6
/7
/8
/9
NOTE
Number 1 for /1 can be omitted. However, when
two or more optional block skip switches are used
in one block, number 1 for /1 cannot be omitted.
(Example)
//3 N123 X100.0 Y200.0 ; Invalid
/1 /3 N123 X100.0 Y200.0 ; Valid
The following figures show the relationship between the timing, when
optional block skip signals (BDT1 to BDT9) are set to 1, and the
ignored information:
1. When BDTn is set to 1 before the CNC starts reading a block
containing /n, the block is ignored.
