RS1A03AAWA by Sanyo Denki

The RS1A03AAWA servo amplifier from Sanyo Denki is a precision motion control device within the R SANMOTION Servo Drives series, designed for industrial automation applications. This servo driver supports a Motor Capacity of 0.75 kW and accepts an Input Voltage of 3Ph 200-230V or 1Ph 200-230V at 50/60Hz. It delivers an Output Current of 5.2A and an Output Voltage range of 3Ph 0–326V, ensuring compatibility with a broad range of servo motors. Compact and robust, the unit measures Dimensions (H×W×D) of Approx. 130 × 60 × 170 mm and weighs Approx. 1.0–1.4 kg, making it suitable for constrained cabinet spaces. The driver features a Type designation as a high-performance Servo Driver for demanding industrial environments.

Performance is enhanced through a flexible Command Interface that accepts Analog ±10V and Pulse Train Input signals, enabling multi-directional control. Digital I/O is provided in a Sinking-type (NPN) configuration for straightforward integration with PLCs and automation systems. The amplifier’s Cooling Method is by Natural Convection, eliminating the need for external fans and reducing maintenance overhead. It draws an Input Current of 5.8A in three-phase mode and 0.2A in single-phase mode, balancing efficiency with dynamic response. The driver’s slim profile and modest Weight further facilitate installation in tight assemblies while maintaining mechanical stability.

Engineered for reliability, the RS1A03AAWA operates within an Operating Temperature range of 0 to +55 °C and tolerates Operating Humidity up to 90% RH (non-condensing). The natural convection cooling strategy ensures consistent thermal performance without additional components. Its robust digital and analog interfaces allow seamless integration into advanced motion control systems, supporting precise speed, torque, and position adjustments. Ideal for CNC machinery, packaging lines, pick-and-place robotics, and general automation tasks, this servo amplifier streamlines system design and enhances productivity. Continuous operation in industrial settings is assured through rigorous Sanyo Denki quality standards and comprehensive technical support.
