Product Description:

The DDS03.2-W050-BE45-01-FW is a digital AC servo drive controller built by Bosch Rexroth Indramat for the DDS Drive Controllers series. In an automation cell, it acts as the closed-loop interface between a motion axis and higher-level control, converting commands into regulated current for synchronous or induction motors. When used with compatible power supplies, the unit supports coordinated multi-axis positioning on packaging lines, handling gantries, and machine tools. Its control architecture allows the drive to respond quickly to changing speed and position demands during normal machine operation.

Field integration is handled through a SERCOS interface, so cyclic setpoints and diagnostic data travel over a single fiber loop without proprietary wiring and with synchronized timing between axes. The power section is rated for 50 A continuous output, allowing medium-frame motors to accelerate quickly without additional amplifiers in many general-purpose motion applications. Thermal energy is removed by internal air cooling, and cabinet air passes across the heat sink instead of relying on an external blower. The enclosure has an IP20 rating, which helps protect against finger contact and solid debris in enclosed cabinet installations. The drive operates at ambient temperatures from 0–45 °C and can be installed up to 1000 m above sea level before derating applies.

The control loop can process feedback from motors equipped with digital servo feedback or a resolver, which supports mixed motor configurations during retrofits or staged equipment updates. Long-term storage is allowed within a range of -30 to 85 °C, so spare units can be kept in non-climate-controlled stockrooms without damage. Parameter compatibility is listed as Function ID 01, and the unit is part of Line 03 and Version 2. This controller is commonly installed in modular Rexroth drive cabinets where consistent diagnostics and regulated torque are required across multiple axes.
