LM628 Overview
The LM628/LM629 are dedicated motion-control processors designed for use with a variety of DC and brushless DC servo motors, and other servomechanisms which provide a quadrature incremental position feedback signal. The parts perform the intensive, real-time putational tasks required for high performance digital motion control. The host control software interface is facilitated by a high-level mand set.
