The example in the above illustration has been greatly simplified. In actual operation, each
register can be controlled from the user program.

Set the position control mode to ON.
Send RUN command to driver.
When IB00303 turns ON, the direc-
tion of rotation is reversed.
When IB00304 turns ON, the fixed speed
feed starts.
Rapid traverse speed (RV): 5,000,000
pulses/min.
Execute the fixed speed feed (FEED)
motion command.
When IB00304 turns OFF, the axis
decelerates to a stop.
When the axis stops, the positioning
completed signal (IBC000D) turns ON.
