Product Description:

The RS2A03A0AA0 is a servo amplifier manufactured by Sanyo Denki for the R SANMOTION Servo Drives series. Intended for industrial automation, the drive converts controller-level motion commands into three-phase power that moves synchronous servomotors. By supervising current, velocity, and position loops inside a single housing, it enables conveyor sections, pick-and-place axes, and indexing tables to reach commanded profiles quickly and hold them with repeatable accuracy.

The amplifier draws its mains supply from 200 V AC and can deliver a continuous phase output of 30 A, matching medium-inertia motors commonly used in packaging lines. A closed-loop bandwidth of 600 Hz lets the current regulator settle within a few milliseconds after each command step. Combined with a programmable speed control range of 1:5000, the axis can creep for alignment or accelerate to full throughput without retuning. Motion planners may choose among speed, torque, or position control modes; each mode is executed by sinusoidal pulse-width modulation that keeps motor vibration low. Regenerated energy is routed to an integral dynamic brake, allowing fast stops during safety trips. Analog command inputs accept ±2.0 V references for both speed and torque channels.

Power electronics use a sinusoidal IGBT PWM drive architecture that minimizes switching loss while maintaining smooth phase waveforms. The amplifier can operate at ambient temperatures up to 55 °C and at installation heights up to 1000 m; output derating is required above either limit. Humidity tolerance is specified at 90% RH, so cabinets must prevent condensation from reaching the unit. The amplifier reads rotor position through a serial motor encoder, but it does not provide a connection for an external encoder. Separate ±2.0 V torque-command inputs and ±2.0 V ±15% torque-limit inputs allow the machine controller to cap shaft force during delicate assembly cycles without changing the main motion parameters.
