Product Description:

The DDS02.1-A100-DS50-00-FW is a digital AC servo drive controller manufactured by Bosch Rexroth Indramat in the DDS Drive Controllers series. The unit acts as the regulated power stage between a PLC or CNC master and a compatible synchronous motor, converting incoming energy into controlled motor current for coordinated axis motion. This allows conveyors, pick-and-place axes, and assembly tools to follow commanded speed and position changes with stable closed-loop response. It also supports synchronized motion where multiple axes must respond predictably to commands from the control system. Internal pulse-width modulation helps the controller deliver smooth motor operation during frequent starts, stops, and direction changes in industrial automation.

The drive supplies a continuous phase current of 100 A, which supports medium-inertia loads during acceleration and steady operation. Command, status, and diagnostic data pass through a SERCOS interface, providing deterministic fiber-optic communication with strong immunity to electrical noise. The housing has an IP20 rating, so the unit is intended for installation inside an enclosed cabinet. Heat is removed by external air cooling, which requires directed airflow across the heat sink to keep power components within their operating range. Rotor position is returned through digital servo feedback, allowing high-resolution commutation and accurate speed regulation at low and changing shaft speeds.

Continuous operation is approved from 0–45 °C, while storage and transport are permissible between −30–85 °C. Rated performance applies up to 1000 m installation altitude, and operation above that height requires derating because lower air density reduces cooling effectiveness. The unit is version 1 of the DDS line. These operating limits are important when the controller is mounted in a cabinet with other heat-generating equipment, since airflow and ambient temperature directly affect thermal performance during sustained motion cycles.
