Product Description:

The DDS02.2-W050-BE56-01-FW is a digital AC servo drive controller produced by Bosch Rexroth Indramat for the DDS Drive Controllers series. Within an automation cell, this controller links a motion axis to higher-level control hardware and supplies regulated current to matched servo motors. By combining power conversion, feedback processing, and network communication, it maintains closed-loop positioning for packaging, material handling, and machining equipment. In multi-axis systems, it acts as the electrical interface between the control system and the motor, translating motion commands into controlled torque and speed. It also processes returning motor signals so the axis can correct position error during acceleration, deceleration, and steady-state operation.

The drive communicates over the SERCOS interface, so velocity and position commands move across a deterministic fiber-optic ring. Thermal dissipation relies on internal air cooling, which uses air from inside the control cabinet instead of external ducting. A housing rated to IP20 guards against accidental contact and requires installation inside an enclosure. The unit can deliver a continuous output of 50 A, enabling it to energize medium-frame synchronous motors across an ambient range of 0 to 45 °C. Because cooling air is drawn from the cabinet interior, the surrounding panel layout must allow warm air to rise away from the heat sink. This protective housing is intended for indoor electrical cabinets rather than direct exposure on the machine frame.

Installation is permitted up to 1000 m above sea level before additional cooling or current reduction is required. Two feedback paths, including digital servo feedback for high-resolution encoders and resolver feedback for more vibration-tolerant sensing, are processed to confirm actual position and support closed-loop control. Using either encoder type gives the control loop flexibility when a machine design favors higher resolution or more robust operation. When de-energized, the controller tolerates storage temperatures of -30 to 85 °C, helping protect the unit during transport and idle storage. The product belongs to Line 02. Its connector geometry and backplane pin assignment match adjacent modules, allowing multi-axis stacks to share a single DC bus inside the cabinet.
