Product Description:

The HDS03.1-W100N-HS04-02-FW is a modular drive controller manufactured by Bosch Rexroth Indramat for the HDS Drive Controllers series. Installed in a DIAX04 rack, the unit converts servo commands from a motion CPU into regulated output for power sections that run synchronous or asynchronous motors. By closing the velocity and torque loops directly at the axis, the controller supports accurate positioning and smooth speed profiles in automated machine tools, printing presses, and material-handling cells, thereby improving cycle time consistency across multi-axis machinery.

This model delivers a continuous output of 100 A, so the connected motor can be driven through rapid acceleration phases without current derating. Command data enters the controller over the fiber-optic SERCOS interface, allowing deterministic communication and electronic gearing between multiple axes on the same ring. Thermal management is provided by a Built-in Internal Air Blower that channels cabinet air across the heat sink, eliminating the need for external ducting. Because the controller belongs to the DIAX04 family, it shares back-plane bus timing, wiring conventions, and diagnostic codes with other members of that platform. Hardware identification as Line 03 indicates the third design iteration, which incorporates revised gate drivers and updated microelectronics for higher EMC immunity.

As an HDS Drive Controller in Version 1, the device presents the first firmware and hardware release for its line, guaranteeing parameter compatibility with early DIAX04 power modules. The absence of optional editions is noted in the specification as None, simplifying spare-part selection during maintenance. In mixed racks, the unit can operate beside future revisions while keeping the same mounting footprint because Bosch Rexroth Indramat standardised connector layouts and cooling airflow path across versions. These attributes allow integrators to replace or expand axes without modifying cabinet ventilation or field-bus topology.
