Classification of dedicated control devices that govern the motion control of industrial robots. Includes controller units that precisely control each axis motor of articulated robots, SCARA robots, Cartesian robots, etc., and execute programmed motion patterns. Functions as an integrated control panel with teaching pendant, I/O units, servo amplifiers, and encoder feedback capabilities, enabling automation of welding, assembly, transport, and inspection operations in manufacturing lines. Equipped with PLC communication functions and safety circuit interlocking capabilities, positioned as control equipment procured separately from the robot body.
