When an maximum 8–digit number after address M is commanded, a
32–bit binary code is output to PMC. Maximum input digits are specified
with parameters for this code. This function is used for on/off at the
machine side. A single M code can be commanded in one block. The
following M codes are decoded and output usually:
M00 : Program stop
M01 : Optional stop
M02 : End of program
M30 : End of program and tape rewind
The above M codes can also be output in binary codes.
M98 (sub program call) and M99 (return from sub program) and always
processed in the NC so, signal will not be output.
Some of the following M–code operations are performed within the CNC.
Note, however, that M–code signals are output.
Forming mode and cancel forming mode
Workpiece clamp and unclamp
Nibbling mode and cancel nibbling mode
Punching mode and laser mode
