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 .........M1600+20n (positioning start completed signal)
• Positioning completed..................M1601+20n (positioning completed signal)
(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.
