HDS03.2-W100N-HS91-01-FW
The HDS03.2-W100N-HS91-01-FW is a drive controller produced by Bosch Rexroth Indramat. As an axis module, it forms part of modular DIAX04 drive packs and converts commanded motion profiles into regulated current for connected servo or spindle motors in automated machinery. By closing the loop between numerical controls and motor windings, the unit provides the torque and velocity regulation needed for coordinated positioning, material handling, and process lines in industrial automation. This arrangement lets the controller respond quickly to changes in load and commanded speed during synchronized machine motion.
Its continuous output capability is rated at 100 A, so the power section can deliver that current to a motor during normal duty cycles without thermal derating. Communication with higher-level control systems occurs over the SERCOS fiber-optic interface, which carries real-time setpoints and feedback while maintaining electrical isolation. Because command and feedback data travel on the optical link, the control path stays isolated from electrical noise generated by the power stage. Thermal management relies on a built-in air blower; the fan moves air through the heat sink to keep semiconductor temperatures within limits without external cooling ducts. The unit belongs to the DIAX04 family, so it uses the same general platform as other modules in that system.
The device is part of Line 03 and carries Version 2, indicating its design line and revision level. Placement in the HDS Drive Controllers series gives the unit mounting dimensions that remain consistent with adjacent axes in the same cabinet. That format supports modular installation in multi-axis racks where each drive occupies a standardized slot. Classified as an HDS Drive Controller, it works with supply units, motor feedback cables, and SERCOS loops already used in DIAX04 systems.
