Yaskawa Electric Corporation DR1B-01AC Servopack

The Yaskawa DR1B-01AC Servopack is an AC servo drive (servopack) designed for industrial motion control, delivering closed-loop speed, torque, and position control by converting AC input power into precise servo motor commands. This discontinued DR1 series model is not a standalone controller; it must be installed in a control panel and paired with a compatible servo motor and control system for CNC machinery, robotics, material handling, or automated assembly applications. Technical specs include 200–230 VAC input, 50/60 Hz, 3-phase, input current approximately 0.87 A, and an approximate weight of 4.5 kg. It is typically available as surplus or refurbished, with common replacements including Yaskawa SGDA series servopacks and SGDH (Sigma II) or SGDV (Sigma V) servo drives.
