Product Description:

The DDS03.2-W050-BE41-02-FW is a digital AC servo drive controller produced by Bosch Rexroth Indramat for the DDS Drive Controllers series. It regulates torque and velocity loops for servo axes in automated packaging lines, material-handling stations, and general machinery. The type code places the unit in line 03 with hardware version 2, which keeps it within the DDS platform while using updated control electronics. Installed in a control cabinet, the drive receives setpoints from a motion processor and supplies regulated three-phase power to a connected motor. This arrangement suits coordinated motion tasks where motor current must respond quickly to changing command values.

The controller exchanges real-time data with its master over a SERCOS interface, using an optical ring for synchronized cyclic communication. Its power stage delivers a continuous phase current of 50 A, allowing mid-frame motors to accelerate quickly without thermal overload. Protection is rated at IP20, so the housing helps prevent accidental contact and relies on the cabinet for added protection against dust and moisture. Reliable operation is permitted within 0 to 45 °C, and heat is removed by internal air cooling that draws cabinet air across the heat sink. Cabinet airflow must remain unobstructed so the module can maintain a stable internal temperature during continuous operation. This cooling method also supports compact installation in multi-axis cabinets where several drives operate side by side.

During transport or storage, the electronics can withstand temperatures from -30 to 85 °C, which helps protect internal components before installation. Continuous duty is permitted up to 1000 m altitude, where normal air density still supports the intended cooling performance. The feedback slot accepts either digital servo feedback or resolver feedback, allowing the drive to work with high-resolution encoder systems or more rugged analog feedback devices. This flexibility supports use of the same controller platform across machines that prioritize positioning accuracy, electrical noise tolerance, or straightforward motor matching. It also gives the axis designer more freedom when selecting compatible motor feedback technology for the application.
