Product Description:

The RS1A03AAWFF servo drive is manufactured by Sanyo Denki as part of the R SANMOTION Servo Drives series. Serving as a compact AC amplifier for brushless servo motors, it converts a 200 V class mains supply into precisely timed three-phase outputs. A built-in dynamic brake dissipates regenerative energy during rapid deceleration, helping axes stop within the commanded distance without external resistors. By combining current, velocity, and position loops, the unit supports high-resolution feedback devices and enables tight motion profiles in packaging, pick-and-place, and semiconductor tools.

At the power stage, the amplifier can deliver continuous motor current up to 30 A, providing headroom for acceleration events without thermal derating. Switching devices are arranged in an IGBT PWM sinusoidal drive architecture, so torque ripple and audible noise are minimized while maintaining high efficiency. Closed-loop regulation spans a broad speed window of 1:5000, letting a single motor execute slow positioning moves and rapid transfers under the same control parameters. The incoming line capacity of 0.8 kVA represents the maximum apparent power drawn from the supply. Velocity response has a frequency bandwidth of 600 Hz, enabling precise tracking of command trajectories.

The enclosure measures 160 mm deep, 50 mm wide, and 168 mm tall, so it fits in narrow machine cabinets where space is limited. With a mass of only 1.0 kg, the drive can be mounted on lightweight panels without reinforcement. A main-circuit inrush current of 18 A and a control-circuit inrush current of 40 A must be considered when sizing fuses and contactors, while leakage current remains limited to 0.5 mA for safety compliance. The control and power sections both operate on the 200 V AC class, and the output interface uses an NPN sinking configuration for command signals.
