5. AUTOMATIC OPERATION
183
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. Y200. ;

BDT2 /2

BDT4 /4
BDT5 /5
BDT6 /6
BDT7 /7
BDT8 /8
BDT9 /9
NOTE
1 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. Y200. ; — Invalid
/1 /3 N123 X100. Y200. ;— 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.
