*Takes 3.2 seconds to turn the Motor servo-on for the first
time after the power is turned on.
(1) Activate the input SVON (Servo-on) to turn the Motor servo on.
(2) The output SVST (Servo state) closes when the Motor gets in the servo-on state.
(3) Select the program channel with the inputs of PRG0 to 7 (Internal program channel select).
Fix the selection 1 [ms] before the input RUN activates.
(4) The System executes a selected channel program when the input RUN turns ON.
The positioning operation is controlled by the parameter values of MA (Rotational
acceleration), MB (Rotational deceleration) and MV (Rotational velocity).
(5) The output BUSY (In-operation) closes while the System is executing the contents of the
channel. At the same time, the output IPOS (In-position) is forcibly opened. If the input RUN is
activated while the output BUSY is closing, the warning F5 (Program error) occurs and the
Motor decelerates and stops.
(6) A positioning operation completes when the positioning error counter clears parameter values
of IN (In-position threshold) and IS (In-position stability timer) at the final stage of
positioning.
 If a channel that contains no program is specified, the warning F5 (Program error) occurs.
