Motion controllers suit demanding test systems
Published: 5 January 2012 - Neil Mead
Inmoco has introduced the Magellan family of Motion Control Processors from Performance Motion Devices (PMD), to provide high performance chip-based motion control in scientific, automation, industrial and robotic applications.
The processors in combination with PMD’s Pro-Motion and C-Motion development software, provide over 20 easy-to-use features to improve OEM machine designs and reduce time-to-market. The processors are available in 1, 2, 3, and 4-axis versions for the control of DC brush, brushless DC, microstepping, and pulse and direction motors. Providing designers with a quick means of incorporating motion control functionality into demanding machine designs, they are complete integrated motion control ICs, requiring only an external amplifier to be functional.
With its integrated design, Magellan is the core motion control component in a variety of applications in industries that require high position accuracy, reliability and stability such as clinical blood analysers, semiconductor wafer handling equipment, surface inspection systems, and three-dimensional printing systems. Applications are said to be faster and more accurate with the Magellan processor.
The Magellan units are driven by a host, using either an 8 or 16-bit parallel bus, CANBus 2.0B, or an asynchronous serial port. User-selectable profiling modes include S-curve, trapezoidal, velocity contouring and electronic gearing. Servo loop compensation utilises a full 32-bit position error, PID with velocity and acceleration feedforward, integration limit, and dual bi-quad filters for sophisticated motion control of complex loads.
