NSK EDD Megatorque Motor - 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 is closed at least for the time set in the parameter FW (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.
