The Prodigy/CME Machine Controller Card integrates up to four Atlas digital amplifiers and a full-featured four-axis positioning motion controller on a single printed-circuit card. These advanced amplifiers provide up to a kilowatt of drive capacity with an input voltage range of 12 to 56 V, a continuous current rating of 14 A, and a 25-A peak current rating. The cards come in one, two, three, and four-axis configurations and control the torque, velocity, and position of dc-brush, brushless-dc, and stepmotors. Communications to the card include 10/100 Mbps Ethernet with UDP and TCP protocols, Serial RS-232, Serial RS-485, and CANbus.
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
