HDS03.1-W075N-HT14-01-FW Bosch Rexroth Indramat

Product Description:

The HDS03.1-W075N-HT14-01-FW belongs to the HDS Drive Controllers series manufactured by Bosch Rexroth Indramat. It is applied in DIAX04 multi-axis systems to regulate inverter modules that power synchronous and induction motors, so it handles velocity, torque, and positioning tasks inside automated machinery.

Digital motion commands reach the unit over the SERCOS fiber-optic bus, which allows high-speed cyclic set-point exchange and deterministic diagnostic feedback. The power stage can deliver a continuous output of 75 A, letting it drive medium-to-large servo axes without external amplifiers. Cooling is provided by a Built-in Internal Air Blower; this fan draws cabinet air through the heatsink to keep semiconductor junction temperatures inside rated limits. The controller is part of the DIAX04 family, ensuring form-factor compatibility with adjacent supply modules and I/O racks. Hardware release 1 incorporates the updated gate-drive circuitry introduced for improved short-circuit response and reduced switching losses.

This device is identified in the product line structure as 03, matching firmware and parameter files that target third-generation HDS hardware. There are None of the alternate mechanical or electrical variants sometimes issued for region-specific standards, so spares logistics remain straightforward. The bolded designation HDS Drive Controller indicates its single-slot housing that mates directly with DIAX04 power supplies via a common bus bar, minimizing wiring. A four-digit LED array on the front panel provides status codes that link to commissioning software from Bosch Rexroth Indramat; this arrangement shortens troubleshooting time because alarms are mirrored both locally and on the supervisory SERCOS network.
