HDS03.2-W100N-HS54-01-FW
The HDS03.2-W100N-HS54-01-FW digital controller belongs to the HDS Drive Controllers series and is built by Bosch Rexroth Indramat. It serves as the control section in modular drive racks, converting motion commands from programmable logic controllers into regulated current and voltage for servo axes. In automated machining cells and material-handling lines, it supervises acceleration, deceleration, and position loops while exchanging diagnostic data with higher-level systems through an integrated communication port. The unit installs in the same cabinet bay as the associated power modules, enabling compact multi-axis packages. Sharing the cabinet bay with the power modules helps keep the overall drive package compact inside the control cabinet.
Its command channel relies on the SERCOS protocol carried over a fiber-optic ring, so deterministic telegrams handle setpoints, feedback, and error flags with electromagnetic immunity. The controller can deliver up to 100 A of continuous output current, allowing it to drive medium-to-high torque servo motors without external amplifiers. Placement in the DIAX04 controller family preserves parameter compatibility with earlier DIAX drives used in the same plant. Thermal limits are controlled by a built-in air blower, which draws enclosure air across the heat sink and avoids the need for liquid cooling hardware. The unit is part of Line 03 in the series, which corresponds to the second electronics revision of the HDS architecture. The optical link also helps keep control signals isolated from electrical noise inside the cabinet.
Within that electronics line, the device is released as Version 2. It includes expanded diagnostic objects and updated SERCOS service channels. The official product category is an HDS Drive Controller. The housing contains control logic and IGBT gate drivers, while a separate HVR or HMS power supply furnishes the DC link. Because the DC link comes from an external supply module, the controller is focused on axis regulation and gate control inside the drive assembly.
