AC Servos

Multipurpose AC servos, a combination of servo amplifiers and servo motors, are used to control positioning of machinery, speed and torque, and can be used for various purposes.
“Servo system,” originating from a Latin word, “Servus,” meaning slaves, is a control system which is designed to operate according to instructed commands. The strong feature of this device lies in its high speed and precision of movement, which allows for constant self-examination of its operative condition and produces feedback to avoid discrepancies with any given commands.


Motion controllers combine servo control functions and sequence control functions. It can be applied for various systems, from exclusive stand-alone devices to special production line type devices.
