Product Description:

The HDS03.1-W075N-HA14-01-FW is a modular axis drive controller produced by Bosch Rexroth Indramat and assigned to the HDS Drive Controllers series. It receives reference signals from higher-level motion logic and regulates the inverter stage that powers synchronous or induction motors in industrial automation. By converting command data into controlled current and voltage, the unit supports closed-loop positioning, speed, and torque control across conveyors, packaging equipment, and material-handling cells.

Command information enters the controller through an ANALOG interface, so set-point voltages from PLCs or motion cards determine the target operating point. The unit belongs to the DIAX04 controller family, allowing it to share a common backplane bus, power supply, and diagnostics with other drive modules in the same rack. Thermal regulation relies on a built-in cooling system that uses an internal air blower to move heat away from the power electronics, eliminating the need for external ducting. In the product code, the line designation 03 identifies the performance tier of the drive section, while the continuous output capacity reaches 75 A, supplying adequate peak current for mid-range servo axes.

This hardware is released as version 1, indicating the first electrical and firmware revision for its slot format. The functional class is recorded as an HDS Drive Controller, a designation that ensures compatibility with matching DSM motor modules and central power supplies in the same platform. When configured correctly, the controller’s parameter set, error handling, and device-level diagnostics align with the family’s standard, reducing commissioning time.
