If a 'TIMEOUT' or 'FAULT' occur during a tracking cycle in one axis and the cycle is canceled, the
ACU will retry after 2min again according to the setting of 'Retry after motor fault'
(NEVER/ONCE/FOREVER). The retry is a RESET which activates the 'MOTOR RESET' outputs
of all three axes for a quarter second and delete the fault flags. All target angles are set to the
actual value to suppress an immediate movement of the antenna. This is also valid for tracking
faults like a 'PEAKING FAULT'.
If a fault stay active in one axis and don't disappear during a RESET, the tracking stops the
operation. For example if the polarisation have a fault, azimuth and elevation stop the tracking
operation.
Technical Specification
Position Encoding with three different interface possibilities : Resolver, digital SSI
and potentiometer
Quantization Error : Resolver 16bit: 0.0055??, SSI 13bit 0.044??, 16bit 0.0055??, 17bit
0.0028??, 19bit 0.0007??
Display Position resolution : 0.001??
Interface to beacon receivers selectable --- sat-nms LBRX or analog voltage input
Analog voltage input : 0 to 10V
Option Tracking Accuracy : Better than 5% of receive 3dB beamwidth (RMS). The encoder
coupling and alignment error should not exceed 0.003?? to achieve the specified tracking
accuracy. The influence of antenna structure thermal error is not considered.
