Product Description:

The HDS03.1-W100N-HS03-02-FW is a digital drive controller manufactured by Bosch Rexroth Indramat for the HDS Drive Controllers series. Installed in a cabinet beside power modules, it supplies closed-loop regulation and coordinating signals to servo axes, thereby forming a core component in automated machining and handling equipment.

The unit exchanges cyclic setpoints and diagnostics through the SERCOS fibre-optic interface, which removes analog wiring and ensures deterministic bus timing. Hardware size and software objects follow the DIAX04 platform so it mounts directly into that rack without adaptation. Up to 100 A of rated output current can be delivered to connected drives, giving adequate headroom for medium-power servo and spindle motors. Thermal dissipation is handled by a Built-in Internal Air Blower that pulls cabinet air across the heatsink, allowing operation without an external fan tray. Alignment with corporate design rules means the module shares parameter structures, error codes, and commissioning tools used across Bosch Rexroth Indramat motion products.

Firmware identification shows it belongs to Line 03, and the hardware carries Version 1, defining compatibility with accompanying power supplies and software upgrades. The functional label HDS Drive Controller distinguishes it from supply and interface cards within the same rack.  These attributes place the controller as a stable drive node for installations that need precise current regulation, deterministic communication, and self-contained cooling in a DIAX04 automation system.
