Product Description:

The DDS02.1-W050-DS48-00-FW is a digital AC servo drive controller manufactured by Bosch Rexroth Indramat for the DDS Drive Controllers series. It acts as the power and regulation stage between a motion control system and an asynchronous or synchronous servo motor. Within an automated line, the unit converts commanded setpoints into accurate current and voltage waveforms, allowing machinery to maintain the speed, torque, and position profiles required by CNC stations, packaging machines, and material-handling axes. Its rack-mounted format supports multiaxis layouts in which several drives share a common DC bus and a coordinated diagnostics structure. Because the controller regulates motor current directly, it can support stable acceleration, deceleration, and steady-speed operation across repeated machine cycles.

The primary communication link is the SERCOS interface, which carries real-time setpoints and status data between the controller and higher-level PLCs. Rotor position returns through digital servo feedback, enabling closed-loop regulation that responds within the device's 0.125 ms internal cycle. This closed-loop arrangement helps the axis correct load changes quickly during indexing and continuous motion. The power stage is rated for 50 A, which suits mid-frame Indramat servo motors used on medium-inertia axes. The enclosure has IP20 protection, so the unit must be installed inside a cabinet. Continuous operation is permitted from 0 to 45 °C when cabinet airflow is managed to remove heat from surrounding components.

Installation altitude is limited to 1000 m, because thinner air above that height reduces cooling effectiveness around the inverter section. When the machine is idle, the unit can be stored from -30 to 85 °C without harming internal materials during transport or warehouse storage. Heat produced during operation is removed by air from inside the control cabinet, so the drive relies on internal cabinet circulation rather than outside air. This cooling method helps keep airborne dust from being pulled directly into the electronics. The model is Version 1 within the series. This revision identifies the product generation used for this drive type.
