Product Description:

The HDS03.1-W100N-HA27-01-FW drive controller is produced by Bosch Rexroth Indramat and belongs to the HDS Drive Controllers series. It fits into the modular DIAX04 rack and receives motion commands from a higher-level PLC, converts them to regulated current and voltage, and in this way coordinates the movement of connected servo axes on assembly or machining lines.

Communication with the module is carried out through a ANALOG command interface, so the upstream control transmits velocity or torque set-points as continuous voltage levels that the drive converts into real-time motor currents. The controller belongs to the DIAX04 family, ensuring mechanical and electrical compatibility with other drive cards that share the same bus and power supply. Thermal management is handled by a Built-in Internal Air Blower; the integrated fan channels cabinet air across the heat sink and eliminates the need for external cooling ducts. The device sits in line code 03, indicating the third design generation of the HDS platform. For output capability, the power stage is rated to deliver a continuous motor current of 100 A, allowing it to operate high-torque servo motors without derating under nominal conditions.

In this individual build, firmware and hardware are designated as version 1, so parameter sets prepared for earlier revisions load without adjustment. The product class is identified as an HDS Drive Controller, confirming that it shares diagnostic routines and parameter structures with other HDS units in multi-axis arrangements. The supplier, Bosch Rexroth Indramat, maintains consistent connector layouts across the series, so installation involves only docking the card, engaging the fan plug, and tightening the bus bars.
