Product Description:

The DDS02.1-W025-DL22-01-FW is a digital AC servo drive controller produced by Bosch Rexroth Indramat within the DDS Drive Controllers series. This model governs a single rotary servo motor in production lines, packaging machinery, and material-handling stations where accurate motion is required. It converts DC bus energy from a supply module into phase-controlled output that maintains commanded speed and position while supervising current and thermal limits. That control structure allows the drive to regulate torque demand while coordinating with the higher-level motion system. In multi-axis cabinets, it mounts on a shared backplane and exchanges power and status data with adjacent modules through the system bus.

The controller provides a continuous output of 25 A without derating during normal operating conditions. Its IP20 enclosure is touch-safe but not sealed against airborne oil or moisture, so it must be installed inside a switchgear cabinet. Heat is removed by internal air cooling, which moves cabinet air across the heat sink instead of relying on external airflow. The permitted ambient operating range is 0–45 °C. Installation is allowed up to 1000 m above sea level before lower air density begins to reduce cooling effectiveness.

A digital servo feedback channel returns encoder data so the controller can close the position loop with high resolution and stable speed regulation. This feedback path helps the controller respond to load changes during acceleration and positioning. The unit supports single-axis position control, which suits stand-alone motion tasks on one servo axis without adding unnecessary load to the central PLC. Storage is permitted from -30–85 °C without damaging the electronics when the unit is not in operation. The unit carries Function ID 01, belongs to Line 02, and is Version 1.
