Drive System - RESEARCH CONCEPTS RC3050 User Manual

6 RC3050 Antenna Controller
Programming Group Functions
The programming group modes provide for initial calibration of the controller and also provides a screen for
resetting drive error conditions.
Calibration screens allow the user to calibrate the RC3050 for use with a particular mount.

1.3.4 Drive System

The RC3050 implements several mechanisms for the driving and monitoring of the azimuth, elevation and
polarization axis.
Position Sensing and Limits
The RC3050 senses absolute axis position using feedback from potentiometers (inclinometer for elevation).
The sensed voltage is scaled appropriately for the particular mount. This sensed position is displayed in
angular format.
The boresight of the antenna is displayed for the azimuth and elevation axis. In elevation, this angle is with
respect to the local horizon. In azimuth, this angle is with respect to the centerline of azimuth travel.
The following diagram shows how the range of movement is limited by the RC3050.

STOW
In the azimuth axis, movement in one direction is disabled when clockwise and counterclockwise limit
switches are activated. There is also typically a region in the center of azimuth travel indicating that the
azimuth axis is in a position that will allow for moving the elevation axis down to the stow position.
