  • Magellan MC55110 Motion Processor

Provides Advanced Stall Detection for Step Motors, Alerts Users to Unsafe Conditions
LINCOLN, Mass., Dec. 11, 2006 -- Motion-control chips, cards and modules maker Performance Motion Devices Inc. announces the Magellan MC55110 single-axis, single integrated circuit (IC) motion processor with automatic stall detection. This flexible device, designed specifically for step motor control, alerts the user when the motor has lost steps during motion. Losing steps (stall) typically occurs when the motor's motion has been obstructed, or a system failure has occurred.

Automatic stall detection operates continuously once it has been initialized by the user. To initiate stall detection, the host simply specifies the number of encoder counts per step.

The Magellan MC55110 motion processor is driven by a host microprocessor using an 8- or 16-bit parallel bus, CANbus 2.0B, or an asynchronous serial port. In addition to automatic stall detection, it provides advanced motion features such as programmable PID filter with velocity and acceleration feed-forward, 32-bit position error, and 50 µSec loop time. Trace capabilities provide designers with on-the-fly data storage for analyzing system performance and performing maintenance and diagnostics.

Four selectable profile modes are supported, including S-curve, trapezoidal, velocity contouring and electronic gearing. The MC55110 accepts input parameters such as position, velocity and acceleration from the host and generates the corresponding trajectory. It accepts feedback from an incremental encoder at up to 10 megacounts per second, or from an absolute encoder or resolver at 160 megacounts per second.

The MC55110 is available now; prices start at $24 in OEM quantities. For additional information, visit; e-mail:
