3. POSITIONING SIGNAL
(12) FIN signal (M3219+20n)
When an M-code is set in a point during positioning, travel to the next block
does not take place until the FIN signal state changes as follows:
OFF→ON→OFF
Positioning to the next block begins after the FIN signal state changes as
above.

Timing Chart for Operation Description
1. Once positioning to point 1 beings, M-code 10 is output and
the M-code output in progress signal goes ON.
11
2. After the PLC takes appropriate action, the FIN signal goes ON.
Travel to the next point does not take place unless the FIN
signal goes ON.
12
3. When the PLC's action causes the FIN signal to go ON,
the M-code output in progress signal goes OFF.
4. After the M-code output in progress goes OFF,the PLC takes
appropriate action so that the FIN signal goes OFF.
Positioning to the next point 2 beings through the above steps.
