HDS03.1-W075N-HS70-01-FW
The HDS03.1-W075N-HS70-01-FW is a drive controller manufactured by Bosch Rexroth Indramat for inclusion in the HDS Drive Controllers series. Installed in automation cabinets, it governs servo axes in packaging, printing, and material-handling equipment where synchronized motion and repeatable response are required. The device interprets network commands, shapes power delivered to the motor windings, and supervises protective functions such as overcurrent cutoff. It also manages fault logging and coordinates regenerative braking energy routing on the shared DC bus. This combination supports acceleration, speed regulation, and controlled stopping during fast production cycles.
It exchanges real-time axis data through the SERCOS fiber-optic interface, enabling deterministic telegram cycles among multiple drives on the ring. This communication method keeps command updates and feedback timing aligned across coordinated axes. Continuous motor supply is supported by a power stage rated at 75 A RMS, and this current level supports steady operation on demanding servo axes. Internal temperatures are managed by a built-in air blower that forces air across the heat sink without relying on external cabinet fans. Assembly coding shows Line 03, and the mechanical profile fits 350 mm rack slots used in the modular cabinet system. The control hardware follows the DIAX04 family layout, so connector placement and module arrangement remain consistent across the system.
The controller is Version 1. Within the rack, this revision can operate alongside units of different current ratings while still exchanging diagnostic objects over the backplane bus. Configuration data is stored on a detachable personality module, so axis parameters remain with that module rather than the main chassis. This arrangement keeps removable memory separate from the power section and simplifies service work inside the cabinet.
