Product Description:

The HDS03.1-W075N-HS57-01-FW belongs to the HDS Drive Controllers series supplied by Bosch Rexroth Indramat. As a drive controller, it regulates power delivery to servo and spindle motors within modular DIAX systems, enabling coordinated motion in industrial automation cells. It fits into the DIAX04 platform cabinets and forms part of a multi-axis configuration where each axis receives closed-loop current and velocity control from its assigned unit.

This unit exchanges set-point and status data over the SERCOS fibre-optic interface, allowing deterministic communication with a master motion controller. Within the DIAX04 family, it occupies the system bus and shares a common DC link for energy balancing between axes. Thermal management relies on a Built-in Internal Air Blower; the blower moves cabinet air through the heatsink so that no external ducting is required. The power stage supports a continuous output of 75 A, which defines the allowable motor armature current during sustained operation. Its identification label shows Line code 03, indicating design refinements such as updated gating logic and improved cooling passages compared with earlier lines.

Classified by Bosch Rexroth as an HDS Drive Controller, the device carries Version code 1, meaning the hardware and firmware set are the first release for this line and are not interchangeable with later revisions without parameter conversion. There are None of the optional variant letters that usually denote special I/O or feedback expansions, simplifying spare-part selection. The build and test processes applied by Bosch Rexroth Indramat ensure interface compatibility across the entire DIAX04 rack, so the controller can be combined with auxiliary supplies, mains filters, and neighbouring axis modules of identical or different current ratings without additional configuration effort.
