4-axis versions, the Prodigy card has motion control features including trajectory generation, servo loop closure, quadrature signal input, motor output signal generation, performance trace, on-the-fly changes, and commutation. The cards use high-density logic circuitry for motion control functions programmed in C/C ++ or Visual Basic language. The features include S-curve trapezoidal, velocity contouring, electronic gearing, and user-generated profile modes. The cards provide servo loop rates of up to 50 µ sec/axis, eight µ count/sec quadrature encoder input rate, high-speed motion trace for servo tuning diagnostics (with 40 kb onboard dual-port memory), and pulse and direction output of up to 5 µ pulses/sec.
