APPENDIX4 EXAMPLE PROGRAMS

4.1 Reading M Codes

An example of a program for reading an M code on completion of positioning start

or on completion of positioning is shown here.

The distinction between positioning start completion and positioning completion is

made with the following signals.

• Positioning start completed .........M2400+20n (positioning start completed signal)

• Positioning completed..................M2401+20n (positioning completed signal)

[Program Example]

(1) A program that outputs the M code for axis 1 from Y000 to Y00F to an external

destination on completion of positioning start and after conversion to BCD code,

is shown here.
