7I49 is a 6 channel resolver interface with 6 additional +-10V analog
outputs. The 7I49 is intended for applications that read standalone
resolvers, as the 7I49 generates the resolver reference excitation. The
7I49 can be used with 1:1 and 1:2 transformation ratio resolvers. The
7I49 has approximately 14 bits of resolution and 12 bits of absolute
accuracy. The 7I49 FPGA interface module allows velocity and absolute
position readout from the host. The 7I49 has selectable excitation frequencies, from 2.5 KHz up to 10 KHz. Host
position readout is updated at 256 times the excitation frequency to
reduce aliasing when host sampling is not synchronous with the
excitation frequency. Velocity resolution is approximately 1 RPM. The
7I49 uses a oversampling A-D followed by a tracking filter. Filter
coefficients may be changed to trade off noise versus acceleration
tracking ability. All resolver and analog I/O is via 3.5 MM pluggable
screw terminal blocks. The 7I49 requires a single 5V power supply.
