Product Description:

The DDS02.1-W100-DA11-01-FW is a closed-loop axis controller developed by Bosch Rexroth Indramat. It is intended for mounting inside multi-axis cabinets, where it converts higher-level motion commands into regulated current for servo motors used in industrial handling machines, machining centers, or packaging lines. In this role, it receives command values from the upstream controller and translates them into motor current for the required motion profile. Closed-loop regulation helps the axis correct deviations quickly when load conditions change during operation. This makes it suitable for axes that need stable speed control and accurate positioning in repetitive duty.

Command signals reach the drive through an analog interface, so ±10 V references or similar analog setpoints can be processed without fieldbus hardware. Continuous output is supported up to 100 A, which is the maximum RMS phase current available to the connected servo. Heat is removed by air from inside the control cabinet, so the enclosure must provide adequate airflow around the module. Rotor position and velocity are resolved by digital servo feedback, allowing the controller to close its speed and position loops with bit-serial accuracy. Because cooling depends on cabinet air, blocked vents or tightly packed modules can reduce thermal margin during sustained operation.

The controller carries Function ID 01 and belongs to Line 02. It runs at Version 1, indicating the first revision of this design. The unit is part of the DDS Drive Controllers series and uses the mechanical and electrical layout associated with that generation. These identifiers set the controller's functional grouping within the DDS platform. They also distinguish this model from other DDS units that use different command interfaces, current classes, or feedback arrangements.
