4 POSITIONING DEDICATED SIGNALS
(7) FIN signal (M4819+20n) ....................................... Command signal
When a M-code is set in a servo program, transit to the next block does not
execute until the FIN signal changes as follows: OFF
to the next block begins after the FIN signal changes as above.
It is effective, only when the FIN accelaration/deceleration is set and FIN signal
wait function is selected.

POINT
(1) The FIN signal and M-code outputting signal are both signal for the FIN signal
wait function.
(2) The FIN signal and M-code outputting signal are valid only when FIN
acceleration/deceleration is designated in the servo program. Otherwise, the
FIN signal wait function is disabled, and the M-code outputting signal does not
turn on.

and the M-code outputting signal turns on.
2. FIN signal turns on after performing required processing in the

execute until the FIN signal turns on.
3. When the FIN signal turns on, the M-code outputting signal

4. When the FIN signal turns off after the M-code outputting signal
turns off, the positioning to the next point 2 starts.
