Product Description:

The HDS03.2-W075N-HS30-01-FW is a modular drive controller produced by Bosch Rexroth Indramat for the HDS Drive Controllers series. Within an automation cabinet it works as the power stage for a single servo axis, taking commands from higher-level motion processors and regulating current to connected Indramat motors. Its role inside the DIAX04 family is to provide closed-loop velocity and torque control while sharing a common DC bus with neighbouring modules.

The unit accepts set-point data over a SERCOS fiber-optic ring, so parameter downloads and real-time feedback travel on the same deterministic channel. A continuous output of 75 A is available, giving the controller headroom for rapid acceleration and braking cycles without exceeding thermal limits. Heat is removed by a built-in internal air blower; the integral fan pulls cabinet air through the heatsink so no external ducting is required. Hardware identification places the device in Line 03, meaning it shares mechanical dimensions and connector layouts with other third-generation DIAX04 modules, simplifying panel design and spares stocking.

Integration with the broader DIAX04 controller stack is managed through firmware that matches Version 2 hardware, allowing synchronous operation alongside earlier or later axes when required. The drive maintains the electrical and diagnostic conventions of the HDS Drive Controllers series, so commissioning software recognises it immediately and loads the correct object directory. Manufacturing by Bosch Rexroth Indramat ensures component compatibility and lifecycle documentation consistent with other Rexroth motion products, reducing engineering effort during upgrades or retrofits.
