Product Description:

The DDS02.1-W050-DS55-00-FW is a digital AC servo drive controller manufactured by Bosch Rexroth Indramat for the DDS Drive Controllers series. It is intended to regulate synchronous and induction servo motors in automated machinery, providing controlled torque, speed, and position response for cabinet-based motion systems. In operation, the unit converts drive power into regulated motor current so connected axes can follow commanded motion profiles with consistent response. With line 02 hardware and version 1 electronics, it serves as a modular axis module that installs in a control cabinet and exchanges real-time motion data with the central automation system.

The drive delivers a continuous output of 50 A, so motor selection and cable sizing must match the available current. Communication with the master control platform occurs over the SERCOS interface, enabling deterministic cyclic data exchange between the controller and the higher-level control system. Thermal management uses internal air cooling, with cabinet air moving across heat-producing components instead of an external blower. The controller operates between 0–45 °C, and the housing has an IP20 rating that protects against accidental contact with internal live parts. Because of this design, the surrounding enclosure must provide suitable ventilation and protection from dust, moisture, and direct contact.

Motor position and velocity are handled through digital servo feedback, allowing closed-loop current and speed control without a separate encoder converter. This feedback method supports accurate regulation when the motor load changes during normal machine operation. Installation is permitted up to 1000 m above sea level before derating is required, which covers most industrial sites. During storage or transport, the unit can withstand ambient temperatures from -30 to +85 °C without damage to internal components. The storage range helps protect the drive during shipping, warehousing, and other periods when the equipment is not energized.
