RC3000 Antenna Controller Chapter 3 Detailed Operation

101

If the mount is equipped with resolvers, two elevation resolver calibration items are included with the

normal inclinometer calibration items.

REF_V:1.69 OFF: 0.0 CONFIG-ELEV

DOWN: 0 UP: 90.0 SF:50.00

LOOK:1 RES: 0.0 REV:0

SET REFERENCE VOLTAGE <0.50 – 3.50>

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

The elev_resolver_offset configuration item defines the offset to be applied to the angle read directly from

the elevation resolver for the purpose of displaying elevation angle. Example: If when at the elevation

reference (deploy) position the raw elevation resolver angle reads 180.0, a elev_resolver_offset of -157.7

will result in a resolver based elevation angle of 22.3.

NOTE: the resolver-based angle is displayed in MANUAL mode when the elevation DOWN limit is active.

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.
