Product Description:

The HDS03.1-W075N-HS55-01-FW drive controller is produced by Bosch Rexroth Indramat within the HDS Drive Controllers series. Serving as the closed-loop power stage between a higher-level motion processor and a synchronous motor, it receives digital setpoints and modulates phase current to govern position, speed, and torque in industrial handling, forming, and packaging equipment. By combining supply bus regulation with axis control in one enclosure, it simplifies machine layouts and maintains coordinated motion across multi-axis assemblies.

The controller exchanges cyclic and asynchronous data over the SERCOS fieldbus through a fiber-optic ring, guaranteeing jitter-free timing for velocity and torque loops. Membership in the DIAX04 family aligns its parameter structure and back-plane connectors with common supply modules used throughout the platform. Waste heat is removed by a built-in internal air blower, so airflow inside the cabinet is sufficient and no external ducting is required. A continuous output of 75 A equips the unit for mid-range servo motors driving conveyors, gantries, or tool heads. Identification as Line 03 links this hardware to a particular mechanical footprint and terminal orientation, which aids direct replacement during service.

Configuration coding lists Version 1, defining the firmware baseline and diagnostic telegram set expected by the master controller. The product classification HDS Drive Controller also establishes permissible ambient conditions and protective functions such as short-circuit shutdown and overtemperature monitoring. Because the catalog lists no other versions, integration engineers can standardize documentation, spare parts, and parameter files without tracking optional cooling kits, programmed feature blocks, or communication variants during long-term production schedules and maintenance.
