Product Description:

The HDS03.1-W100N-HS54-01-FW is a modular drive controller manufactured by Bosch Rexroth Indramat and assigned to the HDS Drive Controllers series. Installed in a DIAX04 multiaxis rack, the unit receives motion commands and generates controlled current and voltage for servo amplifiers, allowing coordinated positioning, contouring, and velocity regulation on production machinery. Its role is to link higher-level CNC or PLC systems to the power stages so that each mechanical axis follows digital setpoints with consistent dynamic response inside industrial automation cells.

This controller communicates with external motion processors through the SERCOS fiber-optic ring, a deterministic interface that transmits setpoints, actual values, and diagnostic data in real time. Inside the rack it is recognized as part of the DIAX04 family, meaning parameter structures and firmware files align with other DIAX components for straightforward axis substitution. The power section is specified for a continuous load of 100 A, so the downstream drive modules can draw high surge currents without forcing the supply to fold back. Its identification tag lists Line 03, which marks the functional design level and determines compatible control cards and configuration tools.

Thermal management is handled by a Built-in Internal Air Blower that draws cabinet air across the heat-producing components; the associated Cooling Method entry removes the need for external ducts in standard enclosures. The catalog shows no alternate hardware variants, indicated simply as None under the “Other Versions” field, and firmware structures are grouped under Version 1, which fixes the boot code and parameter memory layout for service consistency. Finally, the programming manuals reference the Command Communication Interface label so technicians can match optical cables and ring IDs during commissioning.
