11. PROGRAM CONFIGURATION
NC FUNCTION
65
The variable block word address format with decimal point is adopted as
tape format. See List of Tape Format in Appendix C for details on tape
formats.
Label skip function is valid in the following cases, and “LSK” is
displayed on the screen.
D When power is put on.
D When the NC is reset.
When label skip function is in valid, all codes to the first encountered end
of block (EOB) code are ignored.
The ignored part is called ”Reader part”, and section after the first end of
block (EOB) code, “significant information”.
Information between the control–in and the control–out are regarded as
notes and are ignored.
The reset codes (ISO code: %, EIA code: ER) cannot be used in this part.
The ignored part is called “Notes”.
ISO code EIA code
Control–out ( Channel 2–4–5 on
Control–in ) Channel 2–4–7 on
When a slash and number ( /n) is programmed at the head of a program,
and when the machine is operated with the optional block skip switch n
on the machine operator’s panel on, information in the block commanded
with the /n corresponding to the switch number n is ignored.
If the optional block skip switch n is turned off, information in the /n
commanded block will not be ignored. The block with /n commanded can
be skipped by the operator’s selection.
I can be used for n. The 1 to /1 can be omitted.
Example) /1 N12345 G00 X100.Y200.;
2 to 9 can also be used for the n of the /n.
A parity check is made on the number of punch holes for each input tape
character. If the parity does not match, an alarm occurs (TH check). A
parity check is made on each input data block. If the number of characters
in one block (from the code next to EOB to another EOB) is odd, an alarm
occurs (TV check). The TH or TV check cannot be made on the area
skipped by the label skip function. The TH check is not made on the
command field.A parameter can be used to specify whether the characters
constituting comments are to be counted when obtaining the number of
characters for TV check. The TV check function is validated or
invalidated according to the value set on the MDI panel.
