RS1A15AA by Sanyo Denki

The RS1A15AA AC Servo Amplifier from Sanyo Denki, part of the R SANMOTION Servo Drives series, delivers precise motion control for high-performance industrial automation. With a rated current of 15 A and available current ratings of 15, 30, 50, 100, 150 A, this single-axis amplifier accommodates a broad range of motor sizes and torque requirements. It accepts a power supply voltage of AC 200–230 V (±10%/–15%) at an operating frequency of 50/60 Hz ±3 Hz, ensuring compatibility with global power systems. The unit supports both analog and pulse control interfaces, enabling seamless integration into existing motion control architectures. Featuring a built-in positioning function with configurable registers, it simplifies setup by allowing direct command in mm and pulse position command units. High precision control minimizes overshoot and settling times for demanding positioning tasks.

Performance is further enhanced by a native EtherCAT interface delivering 100 Mbps fieldbus communications for deterministic, low-latency networking. The amplifier’s precision control algorithms, combined with reduced settling time, yield superior dynamic response and repeatable motion profiles. It offers flexible acceleration and deceleration profiles—including straight and S-curve options—to optimize mechanical stress and cycle times. Regenerative energy handling is streamlined via installation compatibility with standard control circuits and an external regenerative resistor integration. Torque limit settings adjustable up to 510% of rated capacity protect the motor and drive from stall conditions. Communication diagnostics and status monitoring are available through standard servo drive protocols, ensuring fast fault detection and maintenance.

Engineered for reliability, the RS1A15AA maintains stable operation under fluctuating supply voltages and supports ±15% variation without performance degradation. Its compact design allows straightforward panel mounting alongside other R SANMOTION Servo Drives, facilitating modular system expansion in factory automation cells. Integration into multi-axis systems is simplified by uniform interface standards and extensive compatibility with third-party motion controllers. The amplifier’s robust construction and high immunity to electrical noise ensure continuous operation in industrial environments. Typical applications include assembly robots, CNC machinery, packaging lines, and semiconductor handling systems where precision, throughput, and uptime are critical.
