Product Description:

The HDS03.1-W100N-HA10-01-FW is delivered by Bosch Rexroth Indramat as part of the HDS Drive Controllers series. In a multi-axis DIAX rack it serves as the regulated power and control stage for servo axes, translating reference signals from a motion controller into precise current for connected motors. This controller provides closed-loop regulation, fault monitoring and coordinated power sharing, enabling reliable motion sequences in automated machining cells, material handling lines and general factory equipment.

The command interface is ANALOG, so ±10 V or 4–20 mA inputs can be used for velocity, torque or position demand without a fieldbus card. Membership in the DIAX04 family defines the backplane connector pattern and status diagnostics available to the higher-level CNC or PLC. Continuous output capacity reaches 100 A, allowing the unit to drive high-inertia axes or multiple parallel-wired motor windings while maintaining stable DC-link conditions. Thermal energy is removed by a built-in internal air blower that circulates cabinet air across the heat sink, eliminating external ducting and keeping the drive within its specified temperature window.

Identification code Line 03 assigns this module to the third mechanical layout of the platform, ensuring connector heights and mounting hole positions match the associated supply units. Hardware is marked as Version 1, so firmware files and parameter tools must correspond to that release when commissioning. The functional label HDS Drive Controller distinguishes it from DDS or HMS models and confirms compatibility with standardized DIAX power supplies and feedback links. Within the HDS Drive Controllers series no alternative build options are listed for this catalog number, simplifying spare-part logistics. Manufacturing support from Bosch Rexroth Indramat includes consistent coding bars and slot keys, allowing quick replacement without wiring changes.
