DDDD
0A051-0 Antenna ERROR Xel DDM
communication
Communication error between PCM and cross-
elevation DDM/DMD/FDM. Check SUB-D connectors
and cables.
0A052-0 Antenna ERROR Ele DDM
communication
Communication error between PCM and elevation
DDM/DMD/FDM. Check SUB-D connectors and cables
0A053-0 Antenna ERROR ISM communication Communication error between PCM and ISM. Check
SUB-D connectors and cables.
0A054-0 Antenna ERROR PMM communication Communication error between PCM and PMM. Check
SUB-D connectors and cables.
0A055-0 Antenna WARNING Azi DDM warning The azimuth motor controller has temporarily
observed an unusual situation for temperature,
voltage, current or velocity. No user interaction
required.
0A056-0 Antenna WARNING Xel DDM warning The cross-elevation motor controller has temporarily
observed an unusual situation for temperature,
voltage, current or velocity. No user interaction
required.
0A057-0 Antenna WARNING Ele DDM warning The elevation motor controller has temporarily
observed an unusual situation for temperature,
voltage, current or velocity. No user interaction
required.
0A058-0 Antenna WARNING PMM warning The polarisation motor controller has temporarily
observed an unusual situation with regards to
temperature, voltage, current or velocity. No user
interaction required.
0A059-0 Antenna WARNING Azi cal. limits Check limits of the calibration result for the azimuth
axis are exceeded. Pointing performance may be
degraded. Info:
0x00000040: End stop detected before expected
limit
0x00000100: Zero width is low
0x00000200: Zero width is high
0x00000400: Zero slack is high
0x00001000: Friction average is high
0x00002000: Friction peak is high
0x00004000: Friction asymmetry is high Zero width
low/high: Zero reference module placement may be
incorrect. Zero slack high: Mechanical slack may be
too high. Friction average/peak high: Mechanical
friction is higher than expected. Friction asymmetry
high: Mechanical imbalance may be too high.
0A05A-0 Antenna WARNING Xel cal. limits Check limits of the calibration result for the cross-
elevation axis are exceeded. Pointing performance
may be degraded. Info: See 0A059-0.
