Product Description:

The HDS03.2-W100N-HS12-0 is a drive controller produced by Bosch Rexroth Indramat and supplied under the HDS Drive Controllers series. The unit belongs to the DIAX04 multi-axis platform and serves as a modular inverter that regulates servo or main-spindle motors in automated machining cells, packaging stations, and material-handling lines. By converting the DC bus of a shared supply into precisely metered three-phase output, it delivers closed-loop speed and torque control to individual axes within a larger motion system. Its modular layout lets one supply section feed several axis controllers in the same rack, which supports coordinated motion across separate drive channels.

The controller exchanges setpoints and diagnostics through the SERCOS optical interface, allowing deterministic communication with CNCs or PLCs and stable timing across the fiber ring. Within the DIAX04 cabinet lineup, the product is part of Line 03 and is listed as Version 2. Drive power devices are cooled by a built-in air blower, so cabinet airflow passes through the heat sink without external ducting and helps maintain consistent thermal conditions during sustained operation. The power stage can deliver a continuous phase current of 100 A, allowing high short-term acceleration demand on connected motors while preserving the controller's continuous current capability.

As an HDS Drive Controller, the device closes current and velocity loops locally while motion profiles stream over the fiber ring, which helps reduce network traffic and maintain sub-millisecond response. The factory-mounted blower stabilizes internal temperatures, helping keep IGBT junctions within safe operating limits when the rack contains multiple active axes. This local control structure supports synchronized positioning, electronic gearing, and axis interpolation across distributed servo modules. It is suited for multi-axis systems where several motors must follow coordinated speed and torque commands at the same time.
