RC3000 Antenna Controller

Chapter 3

Detailed Operation

In addition to the normal azimuth calibration items, two azimuth resolver calibration items are included. No azimuth reference_voltage or scale_factor items are displayed since no azimuth potentiometer will be present.

FG: 0.0

CONFIG-AZIM

CCW:180 CW:180

 

RES: 0.0 REV:0

DISP:1

SET REFERENCE VOLTAGE <2.00 – 3.00>

RES: AZIM RESOLVER OFFSET<+/-300.00 DEGREES>

The azim_resolver_offset configuration item defines the offset to be applied to the angle read directly from the azimuth resolver for the purpose of displaying azimuth angle. Example: If when at the azimuth stow position the raw azimuth resolver angle reads 181.3, a azim_resolver_offset of –181.3 will result in a resolver based azimuth angle of 0.0.

REV: ELEV RESOLVER<0-NORMAL 1-REVERSED>

The elev_resolver_reversed configuration item defines whether the polarity of the elevation resolver matches that of the RC3000 resolver circuitry. If the raw elevation resolver angle decreases as the mount moves up, the elev_resolver_reversed item must be described as reversed.
