Product Description:

The HDS03.2-W075N-HA34-01-FW is a modular axis drive controller built by Bosch Rexroth Indramat for use in decentralized servo systems in the HDS Drive Controllers series. This module receives reference values from higher-level motion processors and modulates output current for a matched power section, providing closed-loop speed and torque regulation for industrial machinery such as material-handling gantries and packaging lines. Its command, power, and diagnostic functions allow compact installation inside DIAX racks while maintaining the deterministic response required for synchronized multi-axis automation.

Within the DIAX platform, the unit belongs to DIAX04 and is part of Line 03, which uses a mechanical layout and connector arrangement shared by other third-generation rack modules. The drive can deliver a continuous motor supply of 75 A, so associated conductors and protection devices must be sized for that load. Motion commands arrive through an analog interface, enabling straightforward integration with legacy PLC analog outputs or velocity cards that transmit ±10 V references. Thermal management is handled by a built-in air blower that circulates cabinet air across the heat sink and keeps semiconductor junctions within limits without external ducting or liquid loops.

The module is an HDS Drive Controller and it is Version 2. In this form, the parameter structure and fault-code format match the DIAX04 generation used by related rack modules, which keeps operation consistent in existing analog control systems. Its compact rack-mount format leaves room for adjacent modules in multi-axis cabinets where several controlled axes share the same enclosure. The controller is suitable for large servomotor axes that need stable speed and torque response during synchronized motion in continuous industrial duty.
