Fig. 12.36 Warning due to an M code ON signal during continuous path control
POINT
If the M code output function is not required, set a "0" in setting item " Da.9 M
code" of the positioning data.
(3) Precautions during control
(a) During interpolation control, the reference axis M code ON signal is turned
ON.
(b) The M code ON signal will not turn ON if "0" is set in " Da.9 M code". (The
M code will not be output, and the previously output value will be held in
" Md.32 Valid M code".)
(c) If the M code ON signal is ON at the positioning start, an error "M code ON
signal ON start" (error code: 536) will occur, and the positioning will not start.
(e) If the PLC READY signal (Y1D) is turned OFF, the M code ON signal will
turn OFF and "0" will be stored in " Md.32 Valid M code".
(f) If the positioning operation time is short during continuous path control, there
will not be enough time to turn OFF the M code ON signal, and a warning
may occur. In this case, set a "0" in the " Da.9 M code" of that section's
positioning data.
(g) In the AFTER mode during speed control, the M code is not output and the
M code ON signal does not turn ON.
