Product Description:

The HDS03.1-W075N-HS70-01-FW belongs to the HDS Drive Controllers series manufactured by Bosch Rexroth Indramat. As an HDS drive controller, it is designed to interface with servo drives and regulate motor torque, speed, and position inside DIAX modular drive cabinets. In an automation cell, this unit receives motion profiles from the upstream control system, supervises power delivery to connected servomotors, and coordinates multi-axis tasks through a fiber-optic command loop.

The command interface is SERCOS, enabling deterministic communication over a light-based ring that carries both control words and status feedback without separate wiring. The power section is rated for 75 A, so the module can supply substantial continuous current to high-torque axes without external boosters. Thermal management relies on a built-in internal air blower; this fan directs cabinet air across the heat sink, eliminating the need for ducted cooling accessories. The unit is part of the DIAX04 controller family, ensuring mechanical compatibility with other DIAX modules and shared configuration tools. Its hardware is categorized under production 03 for the line identifier, which aligns connector positions and onboard processor revisions with adjacent controllers in the same rack.

The firmware bay carries Version 1, indicating the first hardware/software combination for this model and matching parameter files issued at initial release. Within the control cabinet, the unit is grouped with other members of the HDS Drive Controllers series so maintenance teams can standardize spares and diagnostics. The label Bosch Rexroth Indramat printed on the front panel guarantees compatibility with original service utilities and loader programs. As an HDS Drive Controller, it features the standardized gate-array logic for pulse-width modulation and automatic fault recognition.
