General Dynamics SATCOM Technologies 7133B Antenna Controller
General Dynamics SATCOM Technologies (formerly VertexRSI) developed the Model
7133B Antenna Controller for applications requiring low cost and
dependable manual antenna positioning for small and medium aperture
antennas. The 7133B provides 3-axis
(AZ, EL, and POL) control.
Highly reliable, brushless resolvers at the antenna provide accurate
position data to resolvertodigital
converters in the rackmounted
Antenna Control Unit (ACU). DIP switches in the ACU provide convenient
position offset adjustment without the necessity for tedious manual shaft
adjustment at the antenna.
On the control panel, 7segment
displays simultaneously indicate all axis
positions. Momentary contact switches change the position of the antenna
drive control. LED’s indicate if any of the limit
switches trip or if the emergency stop button is engaged.
The 7133B system includes a drive cabinet
that houses motor drive circuitry and provides
“local” control capability. The cabinet housing
comes standard as a NEMA 4Xrated
for outstanding corrosion protection even in the
7133B Rear Panel
Absolute, single-speed brushless (size-11) resolvers
and resolver-to-digital conversion IC?s
(4 volt, 2500 Hz reference signal)
Position Encoding Resolution
14 bit (0.022°)
System Interconnect Cabling
System includes 100 feet of interconnect cabling.
Additional cabling is available up to a maximum of
Contoller/Drive cabinet interface cable is 25/C #22 AWG.
Resolver/Controller cable is 3-shielded pair,
#22 AWG (per resolver).
