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 interfaces via daughter boards --- Resolver, digital SSI
and potentiometer
Quantization Error --- Resolver 16bit: 0.0055°, SSI 13bit 0.044°, 16bit 0.0055°, 17bit
