(2) Infinite Rotation Control
Making the shortcut selection valid and moving the actuator in a specific direction continuously
allows the actuator to be rotated continuously as a motor. The continuous operation can be
done as described below.
[Operation Examples]
This example rotates the actuator by 2 turns and finally stops it at position No.4.

Enter position data assuming
1° = 1mm.
(Example) 1.2 is assumed as 1..
1) Widen the positioning widths of position No.1 to 3 so that they are located before the position at
which deceleration is started.
2) Positioning of position No.1 makes positioning complete signal PEND turned ON before
deceleration is started.
If PEND is turned ON, positioning of position No.2 is executed. Similarly, positioning is repeated
in the order of position No.3 1 2 3 4. Because the normal positioning always gives
position data specified last the highest priority, the actuator can be rotated continuously.
3) If the speeds in position No.1 to 4 are set to be the same, the actuator can be rotated at the
same speed. Then the actuator is stopped at the positioning set in position No.4. The number of
rotations is defined by the number of repeats of position No.1 to 3.

[2] Speed Change During the Movement
Sample use
Control method
The speed of the actuator can be changed while it moves. Positions are used by the number of
speeds. The method of controlling the operation to each position is the same as that described
in [1] Positioning.
The example below describes the case of 2 speeds:
1) In this example, the speed is changed while the actuator moves from the position of 150mm
to the position of 0mm. At first, set the positioning to the target position at the first speed in
position No.2. In the positioning width, set the distance from the speed change position to
the target position. The value is set to 100mm in the example. Thus, for position No.2,
positioning complete signal PEND is turned ON at the position before the target position by
100mm.
2) Set the positioning to the target position at the second speed in position No.3.
3) Start position No.2. Then start position No.3 successively when PEND in position No.2 is
turned ON. In normal positioning, position data specified later has always a priority over
position data specified earlier. Thus, the operation in position No.3 is started on the way of
the operation in position No.2.
In this example, the target positions No.2 and 3 are equal with each other. They may not be the
same. However, setting the target positions to be equal with each other allows the distance from
the speed change position to the target position to be known easily.
To increase in the number of speed change steps, add a position number and operation sequence,
set the speed change position in the positioning width and operate the actuator continuously.
