6.17.7 FIN signal wait function

[Data setting]
[Cautions]
[Operation]
By selecting the FIN signal wait function and setting a M-code at each executing point,
a process end of each executing point is synchronized with the FIN signal, the FIN
signal turns ON to OFF and then the next positioning is executed.
Turn the FIN signal on/off using the Motion SFC program or sequence program.
(1) When the FIN signal wait function is selected, the fixed acceleration/deceleration
time method is used. Set the acceleration/deceleration time within the range of 1
to 5000 [ms] by "FIN acceleration/deceleration" (selecting item) in the servo
program.
Indirect setting is also possible by the word devices (1 word).
(1) If the acceleration/deceleration time is specified outside the setting range, the
servo program setting error (error code: 13) will occur at the start and it is
controlled with the acceleration/deceleration time of 1000[ms].
(2) M-code outputting signal is output to all interpolation axes at the interpolation
control. In this case, turn on the FIN signal for one of the interpolation axes.
(3) When M-code is set at the end point, positioning ends after the FIN signal has turn
OFF to ON to OFF.
(4) When the FIN acceleration/deceleration (Fixed acceleration/deceleration time
method) is set in the constant speed control, the setting for advanced S-curve
acceleration/deceleration is invalid.

FIN signal
1. When the positioning of point 1 starts, M-code 10 is output and
M-code outputting signal turns on.
2. FIN signal turns on after performing required processing in the
Motion SFC program.
Transition to the next point does not execute until the FIN signal
turns on.
3. When the FIN signal turns on, M-code outputting signal turns off.
4. When the FIN signal turns off after the M-code outputting signal
turns off, the positioning to the next point 2 starts.
