Product Description:

The HDS03.2-W075N-HS91-01-FW is a drive controller produced by Bosch Rexroth Indramat as part of the HDS Drive Controllers series. Designed for multi-axis automation, the unit converts digital motion commands into regulated output current for servo power sections, enabling coordinated speed and position control in packaging machines, handling systems, and machining cells. In multi-axis installations, it works with higher-level motion processors to coordinate closed-loop regulation across the rack and help maintain cycle accuracy while minimizing following error. Through its embedded control logic, it also supervises fault handling and parameter storage, ensuring consistent startup behavior during repeated machine operation.

The controller exchanges axis data over the SERCOS fiber-optic ring, and this real-time command communication interface supports consistent cycle times while allowing synchronous position updates without separate encoder wiring. The unit has a 75 A output rating, and this value is the rated current for the maximum continuous load it can deliver before protective derating begins. Thermal regulation is handled by a built-in air blower that directs cabinet air across heat-sink channels so the electronics remain within acceptable temperature limits without external ducts or liquid coolers. The airflow path is internal to the controller, which helps the unit fit cabinets that rely on general enclosure ventilation.

The controller belongs to the DIAX04 family of modular drives. This association keeps parameter structures and slot compatibility aligned within the rack used by the system. The model is identified as Line 03, meaning its layout follows the third design iteration for this controller type. The product is Version 2, which indicates the assigned revision for this unit.
