Servo amplifiers (servo drivers) for high-precision control of servo motors in industrial robots and automation machinery. Includes AC servo amplifiers, DC servo amplifiers, and linear servo amplifiers that perform position control, speed control, and torque control. Achieves accurate positioning and speed control through encoder feedback signals, used in drive systems for CNC machine tools, industrial robots, automatic assembly equipment, and conveyor systems. Products with PLC communication functions, multi-axis synchronous control, and safety features are also included. Distinguished from simple motor controllers and inverters as dedicated drive devices for high-precision feedback control.
