3.3.8 Electronic Limit Stops
The positioner uses electronic limit stops. The positioner does not have mechanical hard
stops. The positioner comes from the factory with electronic limit stops set to the maximum
recommended pan and tilt. The limit stops can be adjusted through the controller.
The electronic limits are set as follows:
• Pan limit stops are set to 400° of rotation (±200°)
• Tilt limit stops are set to 180° of rotation (±90°)
The default limits allow the maximum amount of travel possible from the gearboxes. If the tilt
limit stops are reset to their default settings, it is possible to drive the payload platform into
contact with the chassis connector or positioner body. This will cause damage to the
positioner to occur.
3.3.8.1 Adjust Limit Stops with the Keyboard
To adjust the electronic limit stops with the keyboard:
1. Use the joystick to drive the positioner to the desired electronic limit stop.
2. Press [Set].
3. Press [N] where “N” represents the number which corresponds to the preset being
adjusted. Reference Table 3-2 to determine which number to use to change each
electronic limit stop.

4. Press [Pre]. The electronic limit has been adjusted and the positioner will no longer
move past that point.
Note that it is possible to set the electronic limit stops such that the positioner cannot move
(e.g. setting the clockwise and counterclockwise limits to the same spot). If this happens,
restore the electronic limit stops.
