POINT

If the M code output function is not required, set a "0" in setting item " code" of the positioning data.

Da.10

M

[3]Precautions during control

(1)During interpolation control, the reference axis M code ON signal is turned ON.

(2) The M code ON signal will not turn ON if "0" is set in "

Da.10

M code". (The

M code will not be output, and the previously output value will be held in

"

Md.25

Valid M code".)

(3)If the M code ON signal is ON at the positioning start, an error "M code ON signal start (error code: 536)" will occur, and the positioning will not start.

(4)If the PLC READY signal (Y0) is turned OFF, the M code ON signal will turn

OFF and "0" will be stored in "

Md.25

Valid M code".

(5)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 "M code ON signal ON (error code: 503)" may occur. In this case, set a "0" in

the "

Da.10

M code" of that section's positioning data.

(6)In the AFTER mode during speed control, the M code is not output and the M code ON signal does not turn ON.

(7) If current value changing where "9003" has been set to "

Cd.3

Positioning

start No." is performed, the M code output function is made invalid.
