Product Description:

The HDS03.1-W100N-HT02-01-FW is a modular drive unit produced by Bosch Rexroth Indramat in the HDS Drive Controllers series. As a servo amplifier it partners with matching power sections to regulate motor torque, velocity, and position within multiaxis machining cells, printing lines, and material-handling stations. The controller receives motion commands over a fiber-optic ring and then modulates its output stage so that the connected motor follows the programmed profile without deviation.

The drive exchanges real-time setpoint and diagnostic data through the SERCOS interface, allowing deterministic communication with higher-level PLCs. For axis currents up to 100 A, the power section is dimensioned with bus bars and IGBT devices sized to withstand peak regeneration events common in rapid positioning tasks. It belongs to the DIAX04 family, which standardizes mechanical dimensions and software structure across the range, simplifying cabinet layouts and firmware updates. Thermal management is handled by a Built-in Internal Air Blower; this fan draws air through the heatsink channel so cabinet temperatures remain within component limits while eliminating external ductwork. Continuous development support from Bosch Rexroth Indramat ensures parameter sets and diagnostic tools remain available during the controller’s operational life.

Within the DIAX architecture the controller occupies Line 03, indicating the third hardware generation and confirming compatibility with contemporary supply modules and motor feedback options. Its functional category is identified as an HDS Drive Controller, a designation that groups devices capable of both single-axis regulation and coordinated multi-axis operation. Hardware revision level 1 defines the specific board layout and component tolerances released for production, giving maintenance staff a fixed reference for spare parts. The field code lists “Other versions” as None, so every unit shipped under this identifier shares the same electrical limits and firmware baseline, reducing variability during commissioning and simplifying inventory management.
