Product Description:
The PU0A030EN51S00 servo amplifier belongs to the PU Super Servo Amplifiers series from Sanyo Denki. Designed as a power interface between a motion controller and a 400 W class servo motor, the unit converts AC mains power into controlled current for precision motion. It regulates torque and velocity so compact actuators can follow programmed profiles in packaging machines, pick-and-place gantries, and light assembly stations. The amplifier supports applications that require controlled acceleration, steady operating speeds, and repeatable movement. Its compact design also helps conserve space in crowded machine control cabinets.
The amplifier has a continuous output current rating of 30 A, allowing its power stage to supply sustained motor current without exceeding the stated operating capacity. It accepts either a single-phase or three-phase supply at 200 VAC, providing flexibility for different machine power arrangements. The unit is intended for use with a servo motor rated at 400 W, making it suitable for indexing tables, small conveyors, and other light automation axes. Position feedback is supplied by an incremental encoder with a resolution of 2,000 pulses per revolution, allowing the controller to track small changes in shaft position. This feedback supports closed-loop correction when the motor encounters changing loads or acceleration demands. Proper selection of upstream protection, wiring, and motor components remains necessary for operation within the amplifier’s electrical limits.
The drive uses a wiring-saving incremental architecture that reduces the number of individual connections required for its encoder and control signals. Fewer panel terminations can simplify cable routing and reduce the amount of wiring needed inside compact enclosures. The amplifier is configured for speed control, allowing the connected motor’s velocity to be regulated through the drive’s closed-loop control system. This mode supports machinery that must maintain a commanded speed while responding to changing mechanical loads. The model carries the standard type designation, identifying it as the standard configuration for this amplifier model. External motion commands and encoder feedback work together through the amplifier to maintain stable motor operation during repeated machine cycles.
