Product Description:
The PU0A030EMA1S00-EAS1 is a servo amplifier manufactured by Sanyo Denki for the PU Super Servo Amplifiers series. It accepts a three-phase 200 VAC input and acts as the drive-side link between a motion controller and its servo motor, converting commanded velocity signals into regulated armature currents. The unit is used in multi-axis packaging machines, pick-and-place systems, and semiconductor tooling where tight speed control and rapid recovery from load disturbances are required. Its cabinet-mounted design allows the amplifier to operate as part of a coordinated industrial automation system with multiple controlled axes.
The amplifier provides a continuous output current of 30 A, which the power stage can sustain without thermal derating under the appropriate operating conditions. Sanyo Denki pairs the amplifier with the P50B07040D servo motor, aligning the motor’s inductance, inertia, and current requirements with the drive output. Quadrature feedback is processed at 2,000 P/R, providing position feedback at intervals of 0.18 degrees of mechanical rotation. This feedback resolution supports precise velocity measurement and allows the control loop to respond quickly when the connected load changes. The amplifier uses a mounting pitch and connector arrangement shared with related frame sizes, allowing consistent spacing and cable routing within multi-axis control cabinets.
The drive uses a Wiring-Saving Incremental encoder interface, which reduces the number of feedback connections and cabinet terminations required for installation. The amplifier defaults to the Speed control loop, making it suitable for velocity-regulated conveyors, unwind stands, and other machinery that requires stable rotational speed. Its Standard configuration does not include option boards or special protective coatings. Torque or position control, when required by the application, must be provided through external control layers. The molded encoder connection also keeps related signal and alarm wiring organized as it enters the amplifier, reducing the amount of separate point-to-point wiring inside the enclosure.
