RC3000 Antenna Controller Chapter 3 Detailed Operation
103
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.
