The Apex Signal VME-64SD1 (16) Synchro/Resolver-to-Digital VME Card incorporates up to sixteen (16) single-speed or eight (8) two-speed
transformer isolated Synchro/Resolver-to-Digital tracking converters with extensive diagnostics, digital velocity outputs,
angle change alert, and optional programmable reference supply. Any combination of two-speed and single-speed
channels can be field programmed to any ratio between 2 and 255. Each channel also produces differential (A & B)
incremental encoder outputs (with programmable resolution) and a zero degree marker pulse. Alternatively,
commutation outputs are available 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. For 2-speed usage, 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 maximum allowable misalignment of 90°/gear ratio is exceeded.
This card, even when large accelerations are encountered, never looses tracking, because it incorporates 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 that channel. The angle alert monitors each channel
for the programmed angle difference and sets an interrupt as soon as that threshold is reached. Thus, no polling of
the angle registers is required until an angle has reached the specified difference. 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, on all angle and velocity outputs, assure that valid data is always
available without interrupts or waiting time. Our synthetic reference compensates for ±60° phase shifts, thus
eliminating the need for individual compensation networks. Each channel can be specified for a different voltage or
frequency. A watchdog timer is provided to monitor the processor. Part number, S/N, Date Code and Revision are
stored in permanent memory.
The 64SD1 Apex Signal (16) Synchro-to-Digital VME Card may still be available for purchase and support from Artisan Technology Group beyond End-Of-Life (EOL) by the manufacturer (OEM).
