Product Description:

The HDS03.2-W100N-HA09-01-FW belongs to the HDS Drive Controllers series produced by Bosch Rexroth Indramat. As a drive controller, it forms the link between a higher-level PLC and the power stage that drives servo axes, supplying precisely regulated current loops for coordinated multi-axis motion in industrial automation cells.

This model delivers a continuous output of 100 A, a rating that defines the maximum motor phase current the unit can supply without derating. Command signals enter through an ANALOG interface, so velocity or torque references can be generated by conventional ±10 V sources or current loops. The controller is part of the DIAX04 family, which standardizes hardware dimensions and firmware conventions across multiple power classes for simplified cabinet layout. Thermal management is handled by a built-in internal air blower; the fan draws air across the heatsink to keep semiconductor junctions within specified limits during continuous duty. Within the product hierarchy it sits on line 03, indicating mechanical design features and connector placement shared with other units of the same line.

Design revision 2 incorporates updated gate-drive circuitry and diagnostic routines while remaining backward-compatible with earlier DIAX04 controllers. Classified as an HDS Drive Controller, it supports position, velocity, and torque control modes selectable through parameterization. Integration with the wider HDS Drive Controllers series allows mixed-power axes to share a common DC bus, minimizing overall cabinet footprint. Compatibility with motors, feedback devices, and cables certified by Bosch Rexroth Indramat helps ensure predictable dynamic performance.
