This board incorporates major diagnostics that offer substantial improvements to system reliability, because the user is
alerted to channel malfunction.
This approach reduces bus traffic, because the Status Registers need not be
constantly polled. 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 testing 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 the card, and can be enabled or disabled via the bus.
The (D3) Test initiates a BIT test that disconnects all channels from the outside world and connects them across an
internal stimulus that generates and tests 72 different angles to a test accuracy of 0.05
°. Results can be read from
registers and external reference is not required. Any failure triggers an Interrupt (if enabled). The testing requires no
external programming, and can be initiated or stopped via the bus.
The (D0) Test is used to check the card and the VME interface. All channels are disconnected from the outside
world, allowing the user to write any number of input angles to the card and then to read the data from the interface.
External reference is not required.
Power-On Self-Test (POST): When enabled and saved, POST will initiate the D3 Test upon power-on.
SPECIFICATIONS:
Resolution:
16 bits (up to 24 bits optional for two-speed configuration)
Accuracy:
±1 arc-minute for single speed inputs
±1 arc-minute divided by the gear ratio for two-speed inputs
VME Data transfer:
Data transfers within 200 ns.
Tracking Rate:
18.5 RPS max. at 60 Hz; 150 RPS max. above 400 Hz. Referred to Fine input in a two-
speed configuration
Bandwidth:
Normal is 10 Hz at 60 Hz; 40 Hz at 400 Hz, and 100 Hz above 1 kHz. Can be readily
customized
Input format:
Synchro or Resolver, (see part number)
Gear ratio:
Each channel pair is programmable from 2 to 255
Input voltage:
Resolver: 2-28 VL-L Autoranging, 90 VL-L ; Synchro: 11.8 VL-L , 90 VL-L

min. up to 28 VL-L , 100 k min. at 90 VL-L
Reference:
2-28 Vrms, Autoranging or 115 Vrms. Transformer isolated.
Reference Zin
100 k
min.
Frequency:
50 Hz to 10 kHz (see part number)
Encoder outputs:
Either 12,13,14,15, or 16-bit resolution, (field programmable) and Index marker. 12-bit
resolution is equivalent to 1,024 cycles (4,096 transitions) etc. Differential outputs. The
encoder resolution is fixed and does not change with speed. (Optional, see P/N).
Commutation outputs:
Equivalent to the A, B, C outputs from Hall Effect Sensors for 4, 6 or 8 pole motors
Angle change alert:
Each channel can be set to a different angle differential. When that differential is
exceeded, an interrupt (if enabled) is triggered. Default: “Ch. Disabled”.
MSB=180
°; Min. differential is 0.05°. Max differential that can be programmed is 179.9
degrees.
Phase shift:
The synthetic reference circuit automatically compensates for phase shifts between the
transducer excitation and output up to
±60°.
