7-Segment S-Curve Profile Generation Increases Smoothness, Reduces Wear, Speeds Transfer Times

The Magellan Motion Control IC features a 7-segment s-curve profile that, compared to 3-segment trapezoidal profiles, reduces the change in acceleration resulting in less wear and tear on the system and faster transfer times.

Lincoln, MA (PRWEB) May 11, 2007 -- Performance Motion Devices, Inc. announces the Magellan™ Family of Motion Control ICs with 7-segment s-curve profile generation. Available in 1, 2, 3, and 4 axis versions, these flexible, programmable chips provide users additional control required to eliminate oscillation and reduce vibration for smoother motion and higher throughput. Compared to 3-segment trapezoidal profiles, 7-segment s-curve profiles reduce the change in acceleration, resulting in less wear and tear on the system and faster transfer times.

S-curve profiles are an improvement that applies to both servo and stepper motors. The extra control in this type of profile allows the user to tune moves so that significantly less vibrational energy is injected into the load. This means the load doesn't oscillate at the end of the move, which means faster transfer times, and less wear-and-tear on the machine.

In addition to S-curve profile generation, other selectable profile modes are supported including trapezoidal, velocity contouring, and electronic gearing. Magellan Motion Control ICs accept input parameters such as position, velocity, and acceleration from the host and generate a corresponding trajectory. Magellan makes it easy to program standard functions such as timers, PID control, and input/output management. Communication occurs via a host microprocessor using an 8 or 16-bit parallel bus, CANbus 2.0B, or an asynchronous serial port. Features include programmable PID filter with velocity and acceleration feedforward, 32-bit position error, dual bi-quad filters, 50 µSec loop time, and multi-chip synchronization. Trace capabilities provide designers with on-the-fly data storage for analyzing system performance, tuning servo filters, and performing maintenance and diagnostics. PMD's advanced instruction set supports over 130 commands, providing flexibility and versatility to designers during the application programming.

President and CEO, Chuck Lewin comments, "S-curve profiles are an improvement that applies to both servo and stepper motors. The extra control in this type of profile allows the user to tune moves so that significantly less vibrational energy is injected into the load. This means the load doesn't oscillate at the end of the move, which means faster transfer times, and less wear-and-tear on the machine."

Magellan Motion Processors are available in a single-IC / single-axis version, or in a two-IC / multi-axis version. The IC's are packaged in a 144-pin TQFP, and a 100-pin TQFP. These devices operate at 3.3 V. The Magellan Motion Processor is available now. Prices start at $24.00 for single axis configurations, and $39.00 for multi-axis configurations, in OEM quantities.
