Prodigy is part of a new generation of cost-optimized motion cards that are just now hitting the market. These cards use technologies typically found in consumer products such as high-density logic, low parts count, and high-volume manufacturing techniques to reduce cost. Although they provide every bit as much performance, they cost less than half of what similar, older, cards cost.

Performance Motion Devices, Inc. (PMD) introduces the NEW Prodigy™-PCI Motion Card for multi-axis, high-performance control. Available in 1, 2, 3, and 4-axis versions, the Prodigy card provides advanced motion control features including trajectory generation, servo loop closure, quadrature signal input, motor output signal generation, performance trace, on-the-fly changes, commutation, and much more. Motor type can be software-selected on a per-axis basis, and includes DC brush, brushless DC, step, and microstepping. The card communicates via a PCI bus, CANbus or serial port.

Prodigy-PCI is the latest release of the new Prodigy Family of Motion Cards, designed with PMD's advanced Magellan™ Motion Processor. Programmed in C/C++ or Visual Basic language, these cards utilize high density logic circuitry to provide cost-effective, advanced motion control functions. Card features include S-curve, trapezoidal, velocity contouring, electronic gearing, and user-generated profile modes. The card accepts input parameters such as position, velocity, acceleration, and jerk from the host, and generates a corresponding trajectory. Instantaneous on-the-fly changes can be sent by the user, and external signal inputs can be used to program automatic profile changes.

Prodigy-PCI provides servo loop rates of up to 50 µSec/Axis, 8 Mcount/Sec quadrature encoder input rate, high-speed motion trace for servo tuning diagnostics (with 40 KB onboard dual-port memory), and pulse & direction output of up to 5 Mpulses/Sec. Additional features include limit switch input, high speed position capture, dual loop encoder input, 6-step and sinusoidal commutation, PID filter with feedforward and dual biquad filters, incremental and parallel encoder input, 8 general purpose digital inputs and outputs, and 8 10-bit general purpose analog inputs.

Chuck Lewin, President and CEO of PMD comments: "Prodigy is part of a new generation of cost-optimized motion cards that are just now hitting the market.
