Product Description:

The RS2A05AAAL004EB2PL1 is a servo drive module produced by Sanyo Denki for the R SANMOTION Servo Drives series. It interfaces between a motion controller and a matched servo motor, converting command signals into a regulated three-phase output that governs rotor position in automated machinery. By integrating current regulation and encoder feedback, the unit provides precise shaft control for pick-and-place heads, indexing tables, and packaging axes within multi-station production lines.

This model belongs to the one-axis class, so one amplifier section energizes a single motor. The power stage is rated for 50 A of continuous current and operates within the 200 VAC supply range, matching common factory power systems without a step-down transformer. A dedicated position loop supports position control, with velocity and torque calculated internally from encoder data. Command signals are accepted through an analog or pulse input, enabling ±10 V analog references or differential step-and-direction pulses from CNC or PLC hardware. The onboard counter provides a resolution of 10,000 P/R, resulting in a mechanical position increment of 0.036 degrees per pulse for precise staging. Protective algorithms monitor overcurrent, overvoltage, and regeneration to keep the unit within its thermal and electrical limits during rapid indexing and deceleration cycles.

Feedback integration uses an optical sensing method that minimizes jitter and long-term drift. Both the motor and an auxiliary linear scale can use pulse encoders, allowing the drive to compare multiple position sources in applications that require precise positioning over extended travel. Parameter sets are stored in nonvolatile memory, allowing identical axis configurations to be copied across multiple machines. Cable connectors use a keyed layout compatible with matching accessories, simplifying installation and reducing wiring errors in semiconductor handling, electronic assembly, and other precision equipment.
