Motion Control Card Adds Advanced Servo Filters
Dual bi-quad filters at the output of the PID loop can emulate a large variety of filters, providing reduced resonance, faster transfers and smoother motion
Lincoln, MAPerformance Motion Devices, Inc (PMD) announces the Magellan-PCI Motion Controller with dual bi-quad filters. Available in 1, 2, 3 and 4-axis versions, Magellan-PCI is a high performance motion control card that supports DC brush, brushless DC, micro-stepping and pulse and direction motors. It is ideally suited for demanding applications in medical, scientific, and general automation.
The dual bi-quad filters can produce two polarities of low pass output, as well as high pass, bandpass and notch filters. In addition to bi-quad filters, the card's features include trajectory generation, servo loop closure, quadrature signal input, motor output signal generation, servo trace, on-the-fly changes, and commutation. Communication occurs through a PCI bus, via a serial port or using CANBus. The Magellan-PCI provides servo loop rates of up to 50 uSec/Axis, 5 Mcount/Sec quadrature encoder input rate, and pulse and direction output of up to 5 Mpulses/Sec.
Chuck Lewin, President and CEO of PMD, comments "Standard PID is a useful approach for many applications, but additional filtering is sometimes needed for the most demanding applications. By properly selecting the five gain parameters for each bi-quad, all kinds of programmable filters can be created including bandpass, low-pass, high-pass and more."
Designed with PMD's Magellan Motion Processor, the Magellan-PCI card allows designers to create cost-effective, high performance motion systems using standard C or C++ programming. The card accepts input parameters such as position, velocity, acceleration, deceleration and jerk, and automatically generates the programmed trajectory. On-the-fly changes and PLC-style external signal input/output breakpoints can be used to create application-specific profile changes.
Magellan-PCI is available now for US and North American distribution. Prices start at $638.00 in OEM quantities.
