Product Description:

The HDS03.1-W100N-HS22-01-FW is a drive controller positioned in the HDS Drive Controllers series and manufactured by Bosch Rexroth Indramat. Installed inside a DIAX04 modular rack, the unit serves as the command processor between a motion-control CPU and the connected servo power sections. Its primary task in an automation cell is to translate network set-points into precise torque and velocity directives, supervise drive status, and forward diagnostic data so that multiple axes can be coordinated without external timing hardware.

This controller exchanges data over the real-time optical bus SERCOS, ensuring deterministic slot timing for both command and feedback telegrams. It can deliver a continuous output of 100 A, so high-inertia motors can be accelerated without an additional booster module. Cooling is provided by a built-in internal air blower that channels air through the fin stack to maintain safe semiconductor temperatures during sustained peak duty. The device belongs to the DIAX04 controller family, which standardizes backplane voltage levels, status bits, and firmware update procedures across the rack. Factory indexing lists the unit under Line 03, identifying the third design line that shares identical mounting geometry and bus connectors with earlier lines.

Within the product catalogue, the hardware is labeled as Version 1, a tag that binds it to the initial firmware feature set and diagnostic code table. Bosch Rexroth Indramat confirms there are no other versions for this part, simplifying maintenance inventories. Functionally, it is categorized as an HDS Drive Controller, which means it manages control logic and protective monitoring while relying on a separate supply module for DC bus energy. The nameplate carries the mark Bosch Rexroth Indramat, signifying full mechanical and software compatibility with the DIAX04 series and ensuring that field service tools recognize the module without additional configuration steps.
