Product Description:

The DDS02.1-W050-RA02-00 is a digital AC servo drive controller produced by Bosch Rexroth Indramat as part of the DDS Drive Controllers series. Installed in modular automation cabinets, the unit provides closed-loop current control for synchronous and induction motors used in positioning tables, presses, and material-handling axes. It acts as the link between the motion controller and the motor windings, shaping three-phase power so machines can follow commanded profiles under changing mechanical loads. This control structure helps the connected motor maintain stable torque during acceleration, deceleration, and steady-speed operation. Because the control loops are closed in the drive, response to load changes remains faster than with open-loop power stages.

Command data reaches the drive through an analog interface, allowing ±10 V velocity or torque references without a fieldbus card. The power stage can sustain 50 A of continuous output current, so the connected supply module must be sized for the same demand. Heat generated by switching devices is removed by internal air cooling, and cabinet airflow must keep the surrounding electronics within an ambient range of 0 to 45 °C. The enclosure has an IP20 protection category, so fingers and small tools are kept away from live parts while the unit remains intended for installation in a closed cabinet. Motor position is returned through resolver feedback, giving the controller rotor position information for smooth commutation at low and high speeds.

Full performance is maintained up to an installation height of 1000 m above sea level, which avoids derating at most industrial sites. During storage or shipment, the electronics withstand ambient temperatures from -30 to 85 °C, helping protect internal components before startup. The storage range also allows the unit to be transported or warehoused before installation without immediate climate control. The unit is part of line 02 and version 1. These identifiers distinguish the product revision within the DDS range and help confirm compatibility with related system components.
