Product Description:

The RS2A01A8AA0046B2PL1 is a compact servo amplifier produced by Sanyo Denki for the R SANMOTION Servo Drives series. Designed for multi-axis industrial automation, the unit converts a fixed AC supply into controlled three-phase outputs that command compatible SANMOTION servomotors. It closes current, velocity, and position loops so that pick-and-place stages, feeders, and indexers can follow high-resolution motion profiles. The compact design supports installation in densely populated control cabinets while providing the regulated motor current required for coordinated motion.

The drive can deliver a continuous output of 15 A, providing sufficient phase current for mid-frame servo motors without thermal derating. It operates in position control mode, so the command interface accepts incremental position references rather than pure speed or torque commands. The power stage uses an IGBT PWM sinusoidal drive topology, which produces low harmonic distortion and helps maintain motor efficiency at high speeds. Its frequency response reaches 600 Hz, allowing tight gain settings in demanding pick-and-place or electronic assembly axes. A mains feed of 200 V AC supplies the control logic and power devices, removing the need for a separate low-voltage transformer.

Loads with high inertia can be halted safely because the internal dynamic brake engages within 10 ms. The braking circuit can absorb up to 360 J of kinetic energy per stop, helping manage energy produced during rapid deceleration. Feedback is based on a pulse encoder with an optical disk that provides a resolution of 10,000 pulses per revolution, enabling fine interpolation when paired with the drive’s broad speed-control range. The encoder supplies the position information needed by the closed control loops, while excess regenerative energy is routed to the integrated braking circuit. Despite its control and braking functions, the module weighs only 0.9 kg, which reduces the mounting load in high-density machine panels.
