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.

Major diagnostics are incorporated
to offer substantial improvements to system reliability because the user is
alerted to channel malfunctions. This approach also reduces bus traffic because the Status registers do not require
constant polling. Power-On, Self-Test (POST) diagnostic can immediately initiate (D3) test. See Programming
Instructions for further details. Three different tests (one on-line and two off-line) can be selected:
The (D2) test
°
initiates automatic background bit testing. Each channel is checked every 5 to a test accuracy of
0.05° and each Signal and Reference is always monitored. Any failure triggers an Interrupt (if enabled) and the results
are available in status registers. The testing is totally transparent to the user, requires no external programming, has
no effect on the standard operation of this card and can be enabled or disabled via the bus.
The (D3) test
initiates a BIT test that disconnects all input channels from the outside and connects them across an
internal stimulus that generates and tests 72 different angles to a test accuracy of 0.05°. External reference is not
required. This testing requires no external programming, and can be enabled or disabled via the bus.
The (D0) test
is used to check the card and the cPCI interface. All input channels are disconnected from the outside
world thus allowing user to write any number of angles to the card and then read the data from the cPCI interface.
External reference is not required for this test.
This board can operate over a "C" or "M" operating temperature range (See part number). The "C" version (0°C to
+70°C) uses standard high quality commercial semiconductors. The "M" version (-55°C to +85°C, used for severe
environmental condition, uses high quality extended temperature semiconductors. Conduction cooling, using a thermal
plane and wedge locks, can be specified by adding "W" to P/N. A stiffener improves vibration response. Both sides of
the board can be conformal coated (See P/N). All “M” boards are burned in for 24 hours and cycled from -55°C to
+85°C.
