If positioning with incremental specification is interrupted by a pause command,
the axes will be moved to the original end position after the operation is
restarted. Also, if the axes have been moved or an origin search was performed
after the operation was interrupted, the axes will still be moved to the original end
position.

5-6-1 Introduction
M codes consist of information used to interlock with external devices in posi-
tioning operation processes. External devices are devices connected to the PC.
Example Program The following program shows a practical example of M code usage.
N000 P100 X Declares the program number.. . . . . . . . . . . .
N001 G01 X100 F100 Moves to 100 mm on the X-axis by linear .
interpolation.
N002 M100 Outputs M code 100 to the PC and waits. . . . . . . . . . . . . . .
for OK to perform the next operation.
Proceeds to next block when the M-code
reset is received from the PC.
N003 G01 X0 Moves to 0 mm on the X-axis by linear. . . . . . . . . . .
interpolation.
N004 G79 Declares the end of the program.. . . . . . . . . . . . . . . . .
Timing Chart The following diagram shows the timing of the example program’s execution.
The axis being started, M strobe, M code, and M code reset are provided in the
PC data area interface.

Explanation The following list provides a running explanation of the program’s execution.
1, 2, 3... 1. In block N001, the X-axis is moved to 100 mm by linear interpolation.
2. In block N002, M code 100 is output after the X-axis positioning is com-
pleted; the M strobe is turned ON at the same time to indicate that the M
code has been set.
