Highlights 

The current loop provides software-programmable P and I terms as well as other parameters such as shoot-through protection timing. Two symmetric 3-phase PWM (pulse width modulated) output modes are provided, 6-signal mode and 3-signal mode. Two direct-input analog signals provide current feedback from the drive. Commutation is software-programmable, and can occur using a six-step waveform or using a sinusoidal waveform. Velocity feedback is provided by the quadrature encoder, or via a direct-input analog tachometer signal. Velocity commands are provided by an internal profile generator, by a digital SPI 16-bit data stream, or by direct-input analog signal. A programmable compensation filter closes the loop and determines the motor command.

With over 130 commands, the Magellan Motion Processors provide a flexible and powerful instruction set to initialize and control the motion application, monitor ongoing performance, and synchronize overall machine behavior. Working with the Magellan devices, PMD’s powerful Pro-Motion® GUI makes it easy to graph and analyze system performance, while C-Motion® allows you to develop your own application using C/C++.

To create a complete motion controller, the MC73110 is connected to three half-bridge amplifiers, typically MOSFET or IGBT-based. The MC73110 is packaged in a compact 64-pin PQFP (plastic quad flat pack), and operates from 3.3 V.
