Limit Switches
Forward Limit Switch (LSF)
This is a limit switch for a motor which moves forward. When the forward limit switch is active, that limits all the
forward actions. That makes the forward motor to slow down and stop. However, it is not interfering with reversed
actions. The imit switch can be assigned to any external input X or internal auxiliary relay M.

to Stop Positioning
(3) If the starting point is located on the right of the DOG switch:
The home positioning is moving the sliding table by the home positioning speed and the direction of home
positioning. Until the limit switch is reached, the speed slowing down and then stop. After that, moving the
sliding table by the home positioning speed and the opposite direction of home positioning until the Rear End of
the DOG is separated (the signal turns from “ON” to “OFF”), the speed slowing down and then stop.
Furthermore, it uses the home positioning speed and the direction of home positioning to move the table again
until the Rear End of the DOG is reached, the speed decreases to the creep speed then to finish the home
positioning.
(4) If the starting point has caused the limit switch “ON”:
The home positioning is moving the sliding table by the home positioning speed and the opposite direction of
home positioning until the Rear End of the DOG is separated (the signal turns from “ON” to “OFF”), the speed
slowing down and then stop. Furthermore, it uses the home positioning speed and the direction of home
positioning again to move the table until the Front End of the DOG is reached, the speed decreases to the creep
speed then to finish the home positioning.
Reverse Limit Switch (LSR)
This is a limit switch for a motor which moves reversed. When the reverse limit switch is active, that limits all the
reversed actions. That makes the reversed motor to slow down and stop. However, it is not interfering with forward
actions. The imit switch can be assigned to any external input X or internal auxiliary relay M.

INT interrupt signal
When there is an interrupt signal input, the positioning instructions start pertinent control actions. The interruption
signal must have instant response to reach a higher accuracy of positioning. Hence, the interruption signal through
the external input X0~X7 is necessary for the PLC to control that in the way of interruption.
DV2I speed change signal
To operate the DV2I 2 stages interrupt constant quantity positioning instruction, its speed change signal can be
assigned to an external input X or internal auxiliary relay M.
