RS2A03A2HA5

The RS2A03A2HA5 from Sanyo Denki is a high-performance single-axis amplifier in the R SANMOTION Servo Drives series designed for precision motion control. This amplifier delivers a Motor Power of 0.55 kW and supports a Rated Speed of 2000 min⁻¹, perfectly matched to rotary servomotors with a Motor Size of 130 mm. It features an integrated Encoder Type of 17-bit serial absolute feedback for precise position monitoring. The unit is built with a robust Protection Code of IP65 (optional IP67), ensuring reliable operation in harsh industrial environments. With a compact design and a Motor Mass of just 5 kg, it balances power density and ease of installation.

The RS2A03A2HA5 offers extensive technical capabilities that support advanced control strategies and safe operation. It provides a Brake Rated Voltage of 24 VDC ±10% coupled with a Brake Static Friction Torque of 9.3 N·m for reliable holding performance. At peak stall, the amplifier sustains a Peak Torque At Stall of 7 N·m while maintaining a continuous Rated Torque of 2.6 N·m. The Rotor Moment Of Inertia of 3.1×10⁻⁴ kg·m² ensures rapid acceleration and deceleration characteristics. Seamless coordination with additional drives is enabled via the Compatible Amplifier RS3A03A2HA4, allowing multi-axis synchronization.

Operational features emphasize safety, ease of use, and environmental resilience. The amplifier operates reliably across an Operating Temperature range of 0 to 40 °C (32 to 104 °F), while its Protection Code prevents dust ingress and water spray, minimizing downtime. Built-in overcurrent and encoder error detection functions protect both motor and drive, complemented by regenerative braking and a dynamic brake circuit. Engineers benefit from precise torque control and a wide speed range for high-resolution positioning tasks. Moreover, the low Motor Mass enhances system responsiveness and simplifies mounting, reducing overall system footprint.

Integration into existing automation systems is straightforward thanks to standardized connectors and software compatibility. The RS2A03A2HA5 interfaces via EtherCAT and supports parameter configuration through a dedicated setup program accessed via the CN4 port. Address selection is managed with a 16-position knob, and full communication is realized when interfacing with industrial PCs. Ideal for robotics, packaging, printing, and CNC applications, this amplifier seamlessly integrates into multi-axis configurations for enhanced throughput and precision.
