Product Description:

The DDS02.1-W100-DC01-01-FW is a digital AC servo drive controller produced by Bosch Rexroth Indramat for the DDS Drive Controllers series. The unit serves as the power and control stage between an Indramat supply module and an AC servo motor, converting available bus power into regulated three-phase output that follows drive commands in automated machinery. By controlling motor torque and velocity in closed-loop motion axes, the controller supports positioning tasks in assembly systems, packaging lines, and material handling stations, where coordinated starts, stops, and speed changes must remain stable under changing loads. Its role in the axis drive chain allows the supply module, controller, and motor to operate as one coordinated servo system rather than as separate devices.

Communication with higher-level automation devices is handled through INTERBUS-S, a serial fieldbus that transmits setpoints and status data so the drive can stay synchronized with PLC sequences and return operating information to the control system. Thermal management relies on internal air cooling, so cabinet air moves across the heat sink instead of using an external blower, and panel layout must leave airflow unobstructed to avoid heat buildup around nearby components. The power stage is rated for 100 A, giving the controller the current capacity needed for medium- to high-inertia servo motors during acceleration, deceleration, and continuous motion. Motor position is returned over digital servo feedback, enabling the drive to close its velocity and position loops without analog encoders and helping maintain precise response during repeated axis movement.

The drive uses Function ID 01 and Function ID version 01, which identify the feature set and its first revision. It belongs to Line 02, indicating the second platform used within this product range and separating it from earlier arrangements in the DDS line. The unit is version 1, which distinguishes the build level used for this controller and keeps the product identification clear. These identifiers clarify which control configuration belongs to the drive and help prevent mismatched options within a multi-axis system.
