Product Description:

The HDS03.1-W100N-HS08-01-FW is a drive controller manufactured by Bosch Rexroth Indramat and supplied within the HDS Drive Controllers series. In multi-axis industrial automation racks this module delivers closed-loop regulation to servo drives, letting a PLC coordinate motion via a fiber-optic command link. Its purpose is to convert set-point data into regulated current for connected motors while monitoring feedback to maintain torque and speed accuracy.

Command data reach the controller over the SERCOS interface, an optical ring that carries deterministic telegrams so axis updates remain synchronized across the DIAX network. The power stage is dimensioned for a continuous output of 100 A, enabling the unit to energize medium-to-large Indramat servo motors without external boosters. Thermal stability is maintained by a Built-in Internal Air Blower that moves cabinet air across the heatsink and eliminates the need for ducted cooling. Within the DIAX04 family the module shares a common backplane and parameter structure, streamlining replacement tasks and firmware loading. Integration with existing Bosch Rexroth Indramat safety circuits is supported through the standard HDS front connector.

The unit is catalogued under Line 03, which indicates the third hardware generation with improved gate drivers for lower switching losses. Firmware identifiers show Version 1, so parameter files compiled for earlier revisions require no adjustment. As part of the HDS Drive Controllers platform the module uses uniform mounting dimensions, allowing it to slide into any DIAX04 power rail without re-machining the cabinet panel.
