HDS03.1-W100N-HA40-01-FW
The HDS03.1-W100N-HA40-01-FW is a drive controller from Bosch Rexroth Indramat in the HDS Drive Controllers series. It is used to regulate servo axes in modular cabinets, where it provides the power stage and closed-loop control needed for automated machinery. In modular motion systems, it converts cabinet power into controlled motor current so axes can respond to command changes with predictable speed and torque behavior. Its format suits cabinet-based installations that use plug-in drive modules rather than fully self-contained drives.
This unit exchanges setpoint and feedback signals through an analog command interface, making it suitable for systems that use voltage or current references instead of a fieldbus connection. This arrangement works well when the higher-level controller sends simple reference signals and the drive closes the motor loop locally. Because it is part of the DIAX04 platform, it shares mechanical dimensions and backplane connections with other modules in the same cabinet system. Continuous output capacity reaches 100 A, so the power section can supply substantial motor phase current during normal operation. Thermal management is handled by a built-in air blower, which moves air across the heat sink fins and supports stable cooling inside the enclosure.
The controller is part of Line 03 of the HDS platform, which places it in the third design line used for this product group. It is marked as Version 1, so its parameter structure and diagnostic codes follow the first release level for this controller type. The unit is intended for use with matching power supplies and interface cards from the same platform, which keeps module layout consistent across multi-axis cabinet assemblies. This also helps maintain the same general spacing and mounting approach when several drive sections are installed in one enclosure. The result is a controller that fits naturally into cabinet-based DIAX04 drive systems that rely on analog command signals and high current output.
