The devices support dc brush, brushless dc and stepmotors and communicate via a 16-bit parallel bus, CANbus, or serial port. Other features include S-curve, trapezoidal, velocity contouring, electronic gearing, and user-generated profile modes. The card accepts input parameters such as position, velocity, acceleration, deceleration and jerk. Users can send on-the-fly changes and PLC-style external signal input/output breakpoints program automatic profile changes. Users can software select motor type on a per-axis basis and include dc brushed, brushless dc, pulse and direction, and microstepping output. The PC/104 handles servoloop rates up to 50 sec/axis, 5 Mcount/sec quadrature encoder input, and outputs pulse and direction signals to 5 Mpulses/sec.
