Pan Characteristics - AMX AXB-PT15 POSITRACK CAMERA CONTROLLER Instruction Manual

Installation
The outputs use Pulse Width Modulation (PWM) for speed control. The output voltage values are ±
6 VDC or ±12 VDC. Speed is controlled by varying the duty cycle of the output.

Pin 1 is not required if the lens is powered independently. This feature is controlled by
the AMX/CAM switch on the connector panel. Pins 12-15 are required for Speed
mode but are not required for Positional mode.
Servomotor driven outputs are intended to drive servo-type motors only. The outputs have very low
current (milliampere range) capability. DO NOT attempt to drive conventional motors with these
outputs or you may damage the output drivers. If you are not sure about the motor type, refer to the
Specifications section on page 2 for more information.

Pan Characteristics

The pan drive has a maximum pan range of ± 179° (358° total). Pan travel is capable of being
limited to a restricted range around the center of pan travel by software limits adjustable by the
programmer/end user. Pan limits refer to the horizontal range of motion available to the PosiTrack
unit. These limits are set via the Axcess program. The center position marks the center of the range.
