Users can program a variety of motion profiles including S-curve, trapezoidal, velocity contouring, and electronic gearing. Servoloop compensation uses a full 32-bit position error, PID with velocity and acceleration feed-forward, integration limit and dual biquad filters for sophisticated control of complex loads. The cards provide 32 channels of digital and analog I/O. Additional features include nonvolatile RAM storage, a 468-kbyte dual ported RAM for trace and multidimensional contouring, up to 2 Mbyte of user program space, quadrature and Absolute SSI encoder input formats, and a full complement of motion inputs such as limit switches, index signals, and Hall signal inputs.Performance Motion Devices Inc., 80 Central St., Boxborough, MA 01719, (978) 266-1210, www.pmdcorp.com
