Inspect the vector drive and look for a shorted output. Inspect the encoder belt, encoder connections, encoder gaps and encoder alignment.Īlarm 123 SPINDLE DRIVE FAULT at any spindle speed, and Alarm 2040 VECTOR DRIVE OR SPINDLE AMPLIFIER-SHORT CIRCUIT. The encoder belt is damaged, or the Non-Contact Encoder has a fault Refer to Wye Contactor Voltage Inspection section. There is no voltage from the I/O PCB to the Wye contactor coil. There is an open coil on one of the Wye-Delta contactors.Ĭheck the Wye-Delta connections for arching or burn marks. In this paper new photocentric orbits and component masses are calculated for 4 pairs: $\alpha$ UMa, $\beta$ LMi, $\delta$ And and $\xi$ Aqr.Alarm 2041 VECTOR DRIVE OR SPINDLE AMPLIFIER-OVERLOAD, and/or the spindle load pegs to 200% when any spindle speed is commanded. It is particularly suitable for pairs with large magnitude difference as well as for calculation of the preliminary orbits of new astrometric binaries which will be considered in forthcoming papers. We conclude that this direct combination is an acceptable tool to discover and investigate photocentric orbits with periods from 10 to 55 years and the semi-major axis of apparent ellipses $>$0.08 arcsec. known orbits of Sirius, Procyon, Rasalhague, $\mu$ Cas and others. Some capabilities and limitations of this method are discussed in a comparison of our results with. (CDS, I–266) the photocentric orbits of some FK5/Hipparcos stars are calculated in a direct combination of the Hipparcos data with astrometric ground-based observational catalogues having epochs later than 1939.
