Product Description:

The DDS02.1-W025-DG04-00 belongs to the DDS Drive Controllers series from Bosch Rexroth Indramat. As a digital AC servo drive controller, it converts DC-bus energy into three-phase output for servomotors while exchanging status data with higher-level motion control to maintain precise position and speed regulation. Designed for rack mounting inside a control cabinet, it offloads current and velocity loop processing from the PLC. This arrangement supports coordinated multi-axis motion in packaging lines, material-handling gantries, and robotic fixtures where stable axis response is required.

Its thermal design relies on internal air cooling, so cabinet air moves across the heat sink without external ducts. The controller delivers a continuous phase output of 25 A, so the connected motor and duty cycle must stay within that current level. An IP20 enclosure rating limits use to protected cabinet interiors where contact with debris and fluids is minimized. Electrical components are intended to operate in ambient temperatures from 0 – 45 °C, and added ventilation or derating may be needed above that range. Installation is permitted at elevations up to 1000 m above sea level. Position data is accepted through Digital servo feedback, which supports fast updates for rapid acceleration profiles and accurate loop control.

The product is part of line 02 and uses hardware version 1. These identifiers indicate the controller revision used within the DDS platform and help keep module selection consistent with the intended system layout. During transport or extended shutdown, the electronic parts can be stored in ambient conditions from -30 – 85 °C when the unit is unpowered. That storage range is suitable for warehouse conditions before installation or while the controller is kept as a spare. Rack placement and cabinet airflow still need to suit the cooling path so normal operation can resume without unnecessary thermal stress.
