HDS03.2-W075N-HA34-01-FW
The HDS03.2-W075N-HA34-01-FW is a modular power-conversion module from Bosch Rexroth Indramat. It belongs to the HDS Drive Controllers series and is designed for the DIAX04 multi-axis platform. The unit receives velocity or torque references from a higher-level motion processor and modulates three-phase power for synchronous or asynchronous motors. By adjusting motor current in real time, it helps axes follow commanded changes during acceleration, deceleration, and steady-state operation. This supports coordinated motion, repeatable positioning, and stable process speed in production lines, packaging systems, and handling equipment.
Control data reach the module through an analog signaling path, so the reference value is transmitted as a continuous voltage rather than a serial fieldbus. That arrangement fits systems that use conventional process controllers or analog PLC outputs. It also avoids the need for network-based command transmission when the machine already provides analog reference signals. The unit is part of Line 03 and can deliver up to 75 A of regulated output current for medium-frame servo motors. Thermal energy is removed by a built-in air blower, so no external ducting or liquid cooling is required.
The unit is Version 2, and its diagnostic and parameter data are stored within the drive for normal system operation. It uses the same mechanical footprint and connector pinout as related HDS modules, which helps it fit standard cabinet layouts. In a complete drive system, the controller backplane coordinates axis functions in a shared power supply environment. Diagnostic functions allow the control system to monitor operating status and drive conditions during machine use. The module is intended for continuous duty in enclosures where space and thermal margins are limited.
