7.2.6.3. FIN Mode (Parameter FW > 0)
The output IPOS reports completion of the operation caused by the positioning command.
The IPOS signal shall be outputted for every positioning start command such as the RUN
command (Program start).
The output opens at least for the time set in the parameter IS (In-position stability
timer) to check stability of positioning; even no internal pulse is outputted.
The System confirms the settling condition when the Motor reaches to the target position. It
closes the output IPOS for a time set in the parameter FW when residual pulses in the error
counter is less or equal to the set value of the parameter IN (In-position limit).
When the next positioning command is outputted while the output IPOS is closed, the
output IPOS opens and the positioning starts.

The Motor starts rotating at the rising edge.
The System always confirms completion of positioning every time inputting pulse pauses in the
pulse train command operation. If the intervals of inputting pulses are intermittent, set the
parameter IS longer because the outputting IPOS signal will be unstable.
