Product Description:

The DDS02.1-W015-DS50-01-FW is a closed-loop motion control module manufactured by Bosch Rexroth Indramat for the DDS Drive Controllers series. Designed to regulate torque, velocity, and position of compatible AC servo motors, the unit forms the interface between a higher-level PLC and a motor power stage in automated machinery. Its role is to translate motion commands into controlled motor response while monitoring the feedback loop for stable axis behavior. By processing real-time command signals and motor feedback, it coordinates axis movement so packaging lines, handling robots, and printing equipment can maintain repeatable trajectories under changing mechanical loads.

Command and diagnostic data are exchanged over a SERCOS interface, allowing deterministic fiber-optic communication with the system controller. When connected to a supply module, the drive delivers a continuous output of 15 A, which is the maximum phase current available during steady operation. Thermal energy is removed by internal air cooling, so the enclosure must provide enough airflow for the heat sink. For position verification, the drive uses digital servo feedback, allowing high-resolution angle tracking and quick correction of following errors. The combination of deterministic communication and encoder-based feedback helps the controller respond quickly to load changes without losing position accuracy. Electrical touch protection meets IP20, so the unit is intended for installation inside a cabinet rather than in exposed areas.

The permitted ambient operating range is 0 to 45 °C, and higher surrounding temperatures require derating or improved cooling. When the equipment is powered down, it can be stored between -30 to +85 °C without harming insulation materials. Installation altitude is limited to 1000 m above sea level because thinner air reduces cooling effectiveness. These operating limits should be observed whenever the drive is mounted in enclosed automation cabinets or other temperature-controlled machine compartments.
