Product Description:
The PU0A030EMA1S00 servo amplifier is produced by Sanyo Denki for the PU Super Servo Amplifiers series. Designed for industrial automation, the unit accepts regulated AC input and generates phase-controlled output for a compatible servo motor. In a multi-axis system, it receives motion commands from the controller, processes encoder feedback, and regulates motor current to maintain the commanded velocity or position. This closed-loop operation helps reduce overshoot and mechanical wear while supporting compact control cabinets where wiring space is limited.
The amplifier has a continuous output capacity of 30 A, allowing the power stage to supply the rated current without duty-cycle derating. Its power section operates from a three-phase 200 V AC supply, so associated breakers and contactors must be suitable for this voltage class. The compatible servomotor is the P50B07040D, and the drive parameters are matched to its electrical characteristics for stable torque control. Rotor position is measured by a 2,000 P/R incremental encoder, which provides detailed feedback for accurate speed regulation and indexing. The feedback channel and command conductors use the Wiring-Saving Incremental format, reducing the number of required connectors and simplifying cable routing. The amplifier processes the resulting position pulses in real time so the control loop can correct deviations caused by changing loads or acceleration demands.
The unit is supplied with a Speed regulation profile, allowing it to control motor velocity in response to commands from the connected motion controller. This operating profile uses encoder data to compare actual motor speed with the requested value and adjust output current accordingly. The amplifier has a Standard configuration, with no optional fieldbus card or regenerative braking module installed in the expansion slots. Its housing follows the platform mounting pattern, allowing orderly placement beside related power and control components without requiring excessive cabinet depth.
