HDS03.2-W100N-HA28-01-FW
The HDS03.2-W100N-HA28-01-FW drive controller is produced by Bosch Rexroth Indramat as part of the HDS Drive Controllers series. Acting as a modular amplifier in a multi-axis platform, it converts DC bus energy into three-phase output for servo motors in machining centers, material-handling gantries, and other coordinated motion assemblies. The unit interprets torque or velocity references from higher-level motion processors and regulates current locally, serving as the intermediary between a CNC or PLC and the electromechanical load. Because current regulation is handled inside the module, the higher-level controller can focus on motion commands while the drive responds directly to changes at the motor.
The controller delivers a rated output of 100 A, allowing it to drive medium-to-large permanent-magnet motors without external booster modules. Control references enter through an analog interface, so conversion latency is minimal and compatibility is maintained with legacy ±10 V command cards. This arrangement supports systems that use analog command hardware instead of serial motion links. Thermal energy is extracted by a built-in air blower, so cabinet airflow planning can focus on the drive row rather than individual heat sinks. The module is part of the DIAX04 controller family and belongs to Line 03, which matches the mechanical dimensions and bus connection style used by compatible supply units.
The drive is Version 2 and is classified as an HDS Drive Controller. Revised gating transistors reduce switching losses while preserving the operating profile expected of this unit. When mounted with a TVM or KDV supply, the controller fits the same multi-axis layout and bus structure used by surrounding drive modules. This allows it to work within shared power arrangements that use separate supply hardware and coordinated axis installation.
