HDS04.2-W200N-HT02-01-FW
The HDS04.2-W200N-HT02-01-FW is a modular drive controller built by Bosch Rexroth Indramat for the HDS Drive Controllers series. Within a multi-axis system, it governs power conversion and motion commands for synchronous and asynchronous motors used in machine tools, printing lines, and material-handling cells. When paired with a digital interface rack, the unit converts motion commands into regulated armature current for acceleration, constant-speed operation, and controlled deceleration. This arrangement allows the controller to support coordinated axis motion under PLC supervision. Because the power stage and control functions are combined in one module, the unit can respond quickly to changing load demands during positioning and transfer movements.
The controller communicates with higher-level controls over the SERCOS fiber-optic bus, enabling deterministic telegram cycles and real-time diagnostics. It can deliver up to 200 A of continuous output current without thermal derating when installed within its intended operating conditions. A built-in air blower moves air across the heat-sink fins, so the cooling path is self-contained and suitable for dense rack installation. Within the DIAX04 platform, the unit shares backplane connectors and parameter structures with companion axes. The designation Line 04 identifies the product line used with matching power supplies and auxiliary modules, and the optical link also carries status and fault data for closed-loop coordination.
The module is intended for axis control rather than spindle regulation. The functional subset coded as version 2 includes refined current loops and expanded diagnostic bits compared with the initial release. This supports more stable current regulation during changing load conditions and provides broader operating feedback to the higher-level control. Its modular housing and standardized mechanics support integration into coordinated multi-axis assemblies where consistent control response is required.
