Product Description:

The HDS03.1-W075N-HA05-01-FW belongs to the HDS Drive Controllers series manufactured by Bosch Rexroth Indramat. It functions as a drive controller that closes the loop between a higher-level motion processor and the power stages driving individual servo motors. Within industrial automation cells, the unit handles set-point commands, monitors feedback, and issues fault responses so that axes on machining centres, packaging lines, or material-handling gantries maintain position and speed accuracy.

This controller exchanges set-point data over a ANALOG command communication interface, allowing voltage or current references from a PLC to modulate torque in real time. It is part of the DIAX04 controller family, meaning it slides into a common multiple-axis rack where all supplies and network buses are pre-cabled. A built-in Built-in Internal Air Blower moves cabinet air through the heatsink, maintaining semiconductor temperatures without external ducting. The power section is rated for 75 A of continuous output current; this value sets the thermal and magnetic limits for the motor windings it controls. Product line identifier 03 denotes the third design iteration, ensuring mechanical compatibility with similarly numbered supply and interface modules.

As an HDS Drive Controller the device integrates seamlessly with auxiliary firmware and motion cards released for Version 1 hardware builds. There are None of the alternative factory versions often found in later catalogues, simplifying spare-part selection for maintenance teams. Tight correspondence between the internal blower and the 75-amp rating preserves component life, while firmware tailored by Bosch Rexroth Indramat supports diagnostics, parameter storage, and safe-torque-off routines across the DIAX04 rack without altering cabinet wiring or fieldbus topology.
