Product Description:

The DDS02.2-W100-BE81-00-FW is a drive module produced by Bosch Rexroth Indramat within the DDS Drive Controllers series. It regulates torque and speed for synchronous and induction motors used in automated machinery and assembly stations, where stable current control supports repeatable acceleration and holding behavior. The device forms the axis-level component of a modular drive stack, supplying controlled current so position loops remain stable in packaging, printing, and material-handling systems. In this role, it bridges high-level motion commands and motor current regulation for applications that require synchronized starts, stops, and speed changes.

This controller exchanges real-time motion commands over the SERCOS interface, so it can operate in a fiber-optic ring with CNC or PLC masters at deterministic cycle times. A continuous output capacity of 100 A gives the unit headroom for high-torque axes while allowing neighboring modules to operate from the same power structure. Heat is removed by air from inside the control cabinet, so no external fan tray is required, but cabinet airflow must still carry heat away from the drive section. Rotor position data is accepted through digital servo feedback and resolver feedback, letting the same controller operate motors with optical encoders or analog resolvers. The housing, gating stage, and control card classify the product as a Digital AC Servo Drive Controller, and the output bridge uses pulse-width modulation with software-based parameter adjustment instead of analog trim settings.

The unit belongs to Line 02 hardware and is marked as Version 2. These identifiers indicate the product generation used for this drive type and help distinguish it from other revisions when matching command sections and power components. Its integration follows the conventions of the DDS Drive Controllers series, allowing standardized installation, coordinated operation with adjacent modules, and consistent diagnostics when several axes are deployed together in one control cabinet. The layout also supports the modular rack style used in Indramat systems, where each drive handles one motor axis within the larger machine.
