Product Description:

The DDS02.1-W150-RA01-00 is a digital AC servo drive controller produced by Bosch Rexroth Indramat for the DDS Drive Controllers series. Installed in multi-axis machines, it supplies controlled three-phase power to synchronous or induction servo motors and closes the loop between motion commands and the motor windings. By converting reference commands from higher-level automation systems into regulated current, the unit positions axes with the dynamic accuracy required for material handling, packaging, and machining cells. In a servo system, the controller forms the electrical link between the automation platform and the motor, translating command values into usable shaft movement at the machine axis.

This controller delivers a rated output of 150 A, so a connected axis can accelerate large inertial loads without overloading the drive stage. The housing carries an IP20 rating, which shields live parts from accidental finger contact while leaving the ventilation openings unsealed against dust. Command signals enter through an analog interface, where speed or torque references arrive as voltage levels for closed-loop regulation. Rotor position is returned to the controller by resolver feedback, allowing stable commutation during rapid reversals and changing load conditions. Thermal energy produced by the power electronics is removed by air from inside the control cabinet, so the module relies on enclosure airflow rather than a separate fan mounted on the unit.

The specified ambient range of 0 to 45 °C keeps the unit within its normal operating temperature window, and functional integrity is maintained up to a maximum installation elevation of 1000 m without derating. When the plant is idle, the drive can be stored or transported between -30 to 85 °C without harming insulation materials or electrolytic capacitors. The stated storage range applies when the unit is not energized and helps protect internal electrical parts during handling and warehousing. The unit belongs to line 02 with function ID 01 and version 1.
