Product Description:

The DDS03.1-W050-DA03-01-FW is a digital AC servo drive controller produced by Bosch Rexroth Indramat within the DDS Drive Controllers series. In an automation cell, this unit regulates the current, velocity, or position of a connected servo motor so the motion follows programmed setpoints sent by the host control system. By converting command signals into controlled three-phase output, it closes the electromechanical loop that keeps tooling, conveyors, or axes synchronized with machine logic. This makes the controller suitable for coordinated motion tasks that require repeatable motor response.

The controller communicates with higher-level devices through an analog interface, allowing voltage or current references to dictate real-time motor behavior. Thermal management depends on air from inside the control cabinet, so cabinet airflow must be maintained to remove internally generated heat. The power stage is designed for a continuous output of 50 A, a current level suitable for medium-frame servo motors in packaging or material-handling tasks. All live parts sit behind an IP20 protective housing, so finger ingress is prevented when the unit is mounted in a closed rack. Rotor position signals arrive over digital servo feedback, allowing the drive to calculate speed and torque with the resolution required for precise positioning. This supports closed-loop control during acceleration, deceleration, and holding.

The controller operates at ambient temperatures from 0 to 45 °C, while non-operational storage is permitted from -30 to +85 °C. The stated storage range applies when the unit is unpowered during transport or warehouse storage. Installation height can reach 1000 m above sea level without derating, which suits most factory floors and mezzanine installations. The unit is part of Line 03, with Version 1 and Function ID 01. These identifiers distinguish the controller within the product line.
