RS1A05AL by Sanyo Denki

The Sanyo Denki RS1A05AL drive is a high-performance unit from the R SANMOTION Servo Drives series, designed by Sanyo Denki to deliver precision motion control in industrial automation environments. With a system voltage of AC 200 V and an amplifier current capacity of 50 A, the RS1A05AL supports robust power delivery to rotary servo motors. Its CANopen (CiA DS301, DSP402) communication interface enables seamless integration into distributed control systems, while its operating frequency range of 50/60 Hz ±3 Hz ensures compatibility with global power supplies. The primary function of this servo drive is to manage acceleration, deceleration, and positioning of servo motor loads with high accuracy and repeatability.

The RS1A05AL incorporates advanced features that set it apart in demanding applications. It offers built-in positioning functions and configurable command inputs, allowing the drive to execute complex motion profiles without the need for an external controller. Encoder compatibility includes both battery-backup absolute and wire-saving incremental encoders, ensuring flexible feedback options. Control circuits are powered by an optional 24 V DC control power voltage, and output transistor logic can be selected as NPN or PNP to match system requirements. The drive provides overload and surge protection via automatic power cut-off on overload and integrated surge circuitry. Mounting can be performed on the front or rear of the panel, and the compact physical dimensions simplify installation in space-constrained control cabinets.

Designed for reliable operation in industrial settings, the RS1A05AL functions across an operating temperature range of 0 °C to 55 °C and humidity up to 90 % (non-condensing). It supports both internal and external regenerative resistor configurations for safe energy dissipation during braking, and its wiring arrangement separates high-voltage and low-voltage connectors to maintain signal integrity. Compliance with UL, c-UL, and EN standards ensures adherence to international safety regulations. By combining precise control, flexible feedback, and built-in protection features, the Sanyo Denki RS1A05AL enhances system efficiency and reliability, delivering smooth, accurate motion control for a wide range of industrial automation applications.
