Abstract
The present invention is an integral-type IC for multiple-axis position control to provide highly integrated and modular design for the positioning control of automatic system. The inventive IC comprises a plurality of digital differential analyzers (DDA) with output pulse circuit which convert the position command to pulse form, a plurality of servo motor position closed loop control positioning circuit, and a plurality of counters that works with motor encoder to precisely control the rotation speed and motion position of the motor. Thus the invention the position control function in a single IC.
