DESCRIPTION:

This single slot card contains eight separate transformer isolated Synchro/Resolver-to-Digital tracking

converters, optional 5 VA reference, and extensive diagnostics. The (8) measurement channels also produce

differential incremental encoder (A&B) outputs (with programmable resolution) and a zero degree marker pulse or

Commutation outputs for 4, 6, or 8 pole brushless DC motors that eliminate the need for Hall Effect sensors on the

motor thus eliminating processor time and reducing bus traffic. The S/R/D channels incorporate high linearity digital

velocity outputs, angle change alert and can be field configured for either single speed or multi-speed to any ratio

between 2 and 255. Ambiguity circuits maintain monotonic outputs by compensating for misalignment between the

Coarse and Fine Synchros, however, the processor will set a flag when it senses that the max. allowable misalignment

of 90°/gear ratio is exceeded. The S/R/D channels, even when large accelerations are encountered, never looses

tracking, because they incorporate the unique capability to automatically shift to higher bandwidths. The shifting is

smooth and continuous with no glitches. Tracking rates are only limited to bandwidth restrictions, up to 150 RPS, at 16

bit resolution. The “Latch” feature permits the user to read all channels at the same time. Reading will unlatch the

channel. The use of Type II servo loop processing techniques enables tracking, at full accuracy, up to the specified

rate. A step input will not cause any hang-up condition. Intermediate transparent latches, assure that current valid data

is always available for any channel without effecting the tracking performance of the converters. Each channel can be

specified for a different voltage,frequency or resolution.

To simplify logistics, Part number, S/N, Date code, & Rev. are located in permanent memory locations.
