Product Description:

The HDS03.2-W075N-HS57-01-FW is a modular drive controller manufactured by Bosch Rexroth Indramat within the HDS Drive Controllers series. In an automation cell, the unit forms the closed-loop link between a DIAX04 supply and the servo motors on each axis, executing position, velocity, and torque commands to move mechanical loads along programmed paths. Its rack-mount format lets multiple axes be combined inside one cabinet while keeping wiring, cooling, and diagnostic routines standardized across the installation. That layout supports compact multi-axis assemblies in which the controller works as the power and regulation stage for coordinated machine motion.

Command and diagnostic traffic travels over SERCOS, a real-time fiber-optic ring that maintains deterministic cycle times across the motion network. The power stage provides a continuous output of 75 A, giving the controller headroom for medium-to-large brushless servo motors without requiring an external booster for normal operation. Heat is expelled by a built-in air blower, so ambient air drawn through the housing helps keep semiconductor temperatures within acceptable limits during sustained load. The module is part of line 03, and as a member of the DIAX04 family it uses the same system architecture and diagnostic format as related modules.

The drive controller is version 2, which identifies the second revision of this model. As an HDS Drive Controller, it mates directly with HMS fieldbus cards and HVE supply units for use in multi-axis drive systems. Shared parameter structure and diagnostic handling across the 15 A to 100 A range keep operation consistent within the product line. This arrangement allows the module to fit into existing cabinet layouts that use companion supply and communication modules from the same platform.
