Product Description:
The HDS03.1-W075N-HS47-01-FW is a modular drive controller produced by Bosch Rexroth Indramat as part of the HDS Drive Controllers series. It serves as the power and regulation stage in a DIAX04 multi-axis system, converting motion commands into precisely metered motor current. By housing gate-drive, current sensing, and protection circuitry in one unit, it allows fast servo loop closure and simplifies cabinet wiring for automated machines, machining centers, and handling equipment.
The controller communicates over SERCOS, a deterministic fiber-optic bus that carries set-points, status words, and synchronization data in a single optical ring. Its continuous output capability of 75 A supplies ample current for medium-frame servo motors while preserving overload headroom. Membership in the DIAX04 family aligns its parameter structure, resolver feedback connectors, and service tools with the rest of the platform. Temperature rise is limited by a built-in internal air blower, so airflow is generated locally and requires no external ducting. Mechanical coding links the device to Line 03, meaning it occupies the third mechanical size within the HDS rack and uses the matching plug-in power terminals.
The controller is shipped with Version 1 firmware, establishing baseline functionality that can later be expanded through flash updates when higher-level features become available. Because the release history lists no alternate versions, engineers can specify the module without tracking variant codes during maintenance. The firmware also enables automatic recognition of the HDS Drive Controller product type during network start-up, ensuring parameter blocks and safety interlocks load correctly when the servo chain is powered.
