Product Description:

The RS2A01A0AL0WA0 is a servo amplifier manufactured by Sanyo Denki for the R SANMOTION Servo Drives series. It serves as the interface between the motion controller and an AC servomotor, converting low-level command signals into regulated three-phase power while monitoring feedback to maintain the commanded speed and position. Integrating this unit into an automation cell allows synchronized axis movement, shorter cycle times, and operation without mechanical speed-control components.

The drive supplies a continuous output current of 15 A, allowing it to run medium-frame motors without saturation. At startup, the control circuit draws a peak current of 40 A, while the power stage has an inrush current of 18 A; upstream protection devices must accommodate these transient values. Closed-loop response extends to 600 Hz, so the amplifier can follow high-frequency reference changes with minimal phase error. A speed control range of 1:5000 supports slow indexing as well as full-rate production from the same machine axis. The main circuit accepts three-phase AC input, and feedback is provided through a serial motor encoder. The lack of an external encoder connector simplifies harness design and reduces the number of connections required inside the cabinet.

Pulse patterns are generated by an IGBT PWM sinusoidal drive topology that delivers low-distortion current to the motor. Leakage current is limited to 0.5 mA, permitting connection to sensitive ground-fault monitoring devices. A built-in dynamic brake dissipates regenerated energy and allows rapid deceleration without an external resistor. The power module is rated for AC 200 V mains, covering standard factory supplies from 200 to 230 V. Operation is permitted at altitudes up to 1000 m without derating, allowing the amplifier to maintain its stated performance in many industrial locations. The regulated output and encoder feedback support precise motion during indexing, acceleration, steady-speed operation, and controlled deceleration.
