Motion processor ICs take CANbus onboard
Performance Motion Devices has developed the world's first programmable motion processor to directly support a CANbus interface.
Performance Motion Devices (PMD) has developed the world's first programmable motion processor to directly support a CANbus interface Designed for distributed control applications, these ultra-high-performance motion ICs are available in one-, two-, three- and four-axis configurations

Motion processors capture servo traces
The Magellan family of motion processors incorporates real-time servo trace capture to improve servo tuning performance, optimise motion trajectories, and can be used to capture time sensitive data.

New from Performance Motion Devices, the MC73110 motor control IC features a precision velocity loop for brushless DC motors.
Kit puts motion processor IC through its paces
An integrated board and software package allows designers to evaluate and exercise PMD's Magellan family of motion processors.
They control DC brush, brushless DC, microstepping and pulse and direction motors - providing profile generation, servo loop closure, PLC-style signal manipulation and motor signal generation.
In addition to CANbus communications, Magellan motion processors provide standard features such as programmable PID filter with velocity and acceleration feedforward, while adding advanced features like 32bit position error, dual biquad filters, 50us loop time and multi-axis synchronisation.
Trace capabilities also provide designers with on-the-fly data storage for analysing system performance, tuning servo filters, and performing maintenance and diagnostics.
Four selectable profile modes are supported including S-curve, trapezoidal, velocity contouring and electronic gearing.
Magellan motion processors accept input parameters such as position, velocity, and acceleration from the host and generate a corresponding trajectory.
They accept feedback from an incremental encoder at up to 5Mcount/s or from an absolute encoder or resolver at 160Mcount/s.
Communications to these devices occur via CANbus, 8 or 16bit parallel, serial asynchronous point-to-point, or serial multi-drop.
Chuck Lewin, President and CEO of PMD comments: "For years distributed control has been the watchword of the motion industry, but few high-volume, low-cost, systems were available".
"With the advent of CANbus in dedicated motion ICs, networked motion just got a lot more accessible".
"You can now integrate your own motion module with off-the-shelf sensors, actuators and displays".
"That represents a huge savings in engineering time and cost".
Magellan motion processors are available now in a single-IC/single-axis version, or in a two-IC/multi-axis version.
The ICs are packaged in a 144-pin TQFP and a 100-pin TQFP and operate at 3.3V.
