General Description
The MC1401A is a 2-IC general purpose motion control chipset available in one, two, or four axis configurations. It provides trajectory generation and closed-loop digital servo control for a large variety of servo motors. It uses incremental or absolute encoder position feedback signals, and a DAC or PWM compatible output drive. Axes can be programmed either independently or in synchrony to allow advanced multi-axis motion such as circular and continuous-path profiles.
