Motion Controllers Generate 7-Segment S Curves

The latest Magellan family of motion-control ICs offer 7-segment s-curve profile generation capabilities and are available in 1-, 2-, 3-, and 4-axis versions. Compared to 3-segment trapezoidal profiles, 7-segment s-curve profiles are said to reduce the change in acceleration, resulting in less wear on the system and faster transfer times. Other selectable profile modes are also supported including trapezoidal, velocity contouring, and electronic gearing. The ICs accept input parameters such as position, velocity, and acceleration and generate a corresponding trajectory. Other features include a programmable PID filter with velocity and acceleration feed forward, 32-bit position error, dual bi-quad filters, a 50-µs loop time, and multi-chip synchronization. Available in 144-pin TQFPs and a 100-pin TQFP, prices start at $24 each for single-axis configurations and $39 for multi-axis configurations in OEM quantities.
