7.2.1.4
Motor Shaft Encoders
The shaft encoder mounts to the output shaft of the motor, providing a more precise feedback on
Azimuth position. The controller uses the output of the azimuth encoder to determine the range of
motion from axis point A to point B
.
The information is then processed by the AAQ and displayed as
distance and angular position.

7.2.1.5
Azimuth Resolver (optional)
The on axis resolver may be used for more precise motion control. Resolvers are generally used for the
elevation and azimuth axis. The resolver is an on-axis sensor and is generally located on the pivot points
of the unit to provide highly accurate angular data. This sensor is primarily used in precision movements
such as peaking.
