Product Description:

The HDS05.2-W300N-HS70-01-FW is a drive controller produced by Bosch Rexroth Indramat as part of the HDS Drive Controllers series. It functions as the axis control element inside DIAX modular drive systems, converting motion commands from higher-level automation into regulated current for servo and main-spindle drives. Within industrial automation cells, it coordinates speed and torque loops for multiple machine axes, allowing synchronized positioning, stable feed control, and repeatable cycle timing. By managing these closed-loop responses in the drive rack, the unit supports precise motion on equipment such as transfer systems, machine tools, and packaging lines. That arrangement allows the controller to react quickly to command changes while maintaining stable motor behavior under varying load conditions.

The controller uses a SERCOS fiber-optic interface for deterministic data exchange and synchronized motion profiles between the rack and the higher-level control. The DIAX04 designation places it within the related platform used for coordinated servo systems. Its power section supplies a continuous output of 300 A, so large motors can operate without thermal derating during sustained load. Thermal energy is removed by a built-in air blower, which supports heat sink cooling without an external blower assembly. The unit is Version 2. It also reports measured current and DC-link voltage on every control cycle, supporting real-time monitoring of load changes and bus conditions during rapid acceleration or deceleration.

The product is part of Line 05, which places it within the fifth design line of the series. It uses common mounting dimensions with related rack modules, allowing organized placement in multi-axis cabinets without unusual spacing changes. A standard configuration card can copy startup parameters from an adjacent axis, helping keep settings consistent across the rack. The plug-in terminal arrangement also supports straightforward wiring in modular assemblies. This layout suits machines that place several coordinated drive axes, supply sections, and feedback connections side by side in one enclosure. It also keeps access to service connectors and module fronts aligned across the rack.
