HDS05.2-W300N-HA08-01-FW
The HDS05.2-W300N-HA08-01-FW is a drive controller manufactured by Bosch Rexroth Indramat and belongs to the HDS Drive Controllers series. As a modular axis module, it fits into DIAX04 automation racks to regulate servo power stages in multi-axis machines. The unit converts low-level motion commands into controlled current and voltage patterns for synchronous and asynchronous motors used in industrial automation cells. In operation, it serves as the power and control section for axes that require stable speed and torque regulation under changing loads, especially where several drives share a common rack.
Its command channel uses an analog interface, so velocity or torque references are delivered as ±10 V signals rather than through fieldbus telegrams. This arrangement suits systems that use dedicated motion cards or other external analog command sources. Within the rack, the controller exchanges status words over the back-plane bus, while the external reference remains analog for fast response. The DIAX04 platform gives it matching pinouts and diagnostic behavior with the rest of the system. Thermal management relies on a built-in air blower, which forces cabinet air across the heat sink so no external cooling plate is required. For power delivery, the module has a 300 A rated current, which is the maximum continuous motor phase current it can supply when the DC link is at nominal voltage, making it suitable for high-demand axes such as gantries and spindle drives.
The identification code includes Line 05 and Version 2. These values indicate the product generation and layout used by this controller within the series. The line code separates this unit from other module classes in the same range, while the version number distinguishes it from earlier builds. They are identification details used to distinguish this controller within the product range.
