Product Description:

The HDS03.2-W100N-HS74-02-FW is an AC drive controller produced by Bosch Rexroth Indramat. It belongs to the HDS Drive Controllers series and mounts in a control cabinet to regulate torque, speed, and position for servo or spindle motors in production lines, packaging machines, and material-handling cells. Acting as the interface between the motion control and the power stage, it converts numeric setpoints into controlled three-phase current so connected axes can follow programmed trajectories with repeatable precision, and field-replaceable terminals allow the module to be removed without disturbing adjacent hardware.

The command channel uses the fiber-optic SERCOS ring, which provides deterministic cycle times for position, velocity, and torque commands while returning diagnostics on the same loop. As part of the DIAX04 family, the unit shares cabinet mechanics and bus connectors with other modules in that platform, which supports mixed-axis rack layouts. It can supply up to 100 A of continuous RMS phase current without derating. Thermal energy at this load is removed by a built-in air blower that pulls cabinet air through fin channels. The product is part of Line 03 and uses the corresponding backplane arrangement and matching power components.

The product is Version 2. Front-panel LEDs report communication quality, temperature warnings, and overcurrent trips so operating status can be checked during normal machine operation. A keyed backplane connector helps maintain consistent electrical mating across identical controllers in the rack and reduces the chance of incorrect insertion. The controller is intended for cabinet-mounted multi-axis systems where stable communication, controlled motor current, and clear status indication support coordinated motion on several connected axes.
