Product Description:

The HDD02.2-W040N-HD12 is a modular axis drive controller built by Bosch Rexroth Indramat for the HDD Drive Controllers series. It converts high-level velocity and position commands into regulated three-phase currents for servo motors in automated packaging, handling, and machining lines, closing the loop between PLC motion instructions and mechanical output. Its compact card format allows dense multi-axis layouts inside electrical enclosures used on distributed production cells. By integrating power electronics and control logic on one board, it minimizes cabinet footprint while still delivering dynamic response.

Its command channel is the SERCOS interface, enabling fiber-optic communication for deterministic cyclic data exchange with higher-level controls. Inside the multi-axis platform, the unit belongs to the DIAX04 controller family, so parameter structure, diagnostics, and mounting dimensions match companion axes. Thermal management is handled by internal air cooling from a built-in blower that draws cabinet air across the heat sink. The power stage is rated for 40 A continuous output, allowing the connected servo to deliver sustained performance under nominal duty. The unit is classified as a Drive Controller, which means the power electronics and axis control functions share the same housing.

The product is part of Product Line 02, placing it in the second design generation of this controller platform. The unit is Version 2, which identifies the revision used for this model. These identifiers separate this drive from earlier releases in the same series when documentation, diagnostics, and available function sets are matched to the installed module. They also help keep service-channel behavior and controller responses consistent within systems that use the same generation of modules. That distinction is useful in multi-axis cabinets where several controllers may share the same communication structure but belong to different generations.
