Set the position control mode to ON.
Rapid traverse speed (RV)
(5,000,000 pulses/min)
Driver operation command (RUN)
Execute fixed speed feed (FEED) as the
motion command.
When IB00304 turns ON, rapid traverse
starts in the forward direction.
When IB00304 turns OFF, the axis
decelerates to a stop. When travel is
completed, the positioning completed
signal (IBC000D) turns ON.
