Product Description:

The RS2A03A0AL0W00 is a servo drive manufactured by Sanyo Denki within the R SANMOTION Servo Drives series. It serves as the power and regulation interface between a motion controller and a synchronous servomotor. The drive converts logic-level commands into precisely modulated phase currents that govern rotor speed, torque, or absolute position in industrial automation cells. This closed-loop operation allows connected machinery to respond accurately to changing motion commands and load conditions.

An amplifier capacity of 30 A provides enough output current for rapid acceleration without saturating the drive’s output devices. The incoming power requirement is 200 V AC, matching factory mains used in many 200 V class installations. The drive provides speed, torque, and position control, allowing it to support several types of motion applications. Its current loop has frequency characteristics of up to 600 Hz, supporting fast responses to load disturbances and command changes. Closed-loop velocity regulation spans a ratio of 1:5000, allowing the drive to regulate both low-speed assembly axes and high-speed material-handling equipment. A built-in dynamic brake helps stop the connected motor during controlled shutdowns or fault conditions without requiring a separate braking unit for this function.

Leakage current is limited to 0.5 mA per motor, which supports grounding arrangements in multi-axis systems. The command interface accepts quadrature inputs at up to 1.25 million pulses per second, while forward and reverse pulse trains can reach 5 million pulses per second for high-resolution positioning. The unit has a mass of 1.0 kg, simplifying installation in space-constrained control panels. Feedback is received from a serial motor encoder, and the unit does not include an external encoder port. This arrangement reduces the number of feedback connections required between the motor and drive. Operation is permitted at ambient humidity levels of up to 90% RH and at elevations of up to 1,000 meters without derating. These operating limits accommodate installation in a broad range of indoor production facilities.
