HDS03.1-W075N-HA44-01-FW
The HDS03.1-W075N-HA44-01-FW is a drive controller produced by Bosch Rexroth Indramat for the HDS Drive Controllers series. Within multi-axis DIAX04 racks, it supplies regulated power to servo modules and translates reference commands into controlled motor operation for automated machinery. It acts as the power and regulation stage between higher-level control signals and the connected axes, allowing current and velocity control to be handled in one chassis. This arrangement supports precise motion sequences in packaging, printing, and material-handling lines. Because the controller combines regulation and cooling functions in one housing, it reduces the need for separate supporting hardware inside the rack.
The controller delivers a continuous output of 75 A, which is the maximum phase current available to attached servo drives during continuous operation. Reference data enter the device through an analog command interface, so voltage or current signals from a PLC can directly influence speed or torque setpoints without additional fieldbus hardware. Thermal management relies on a built-in air blower that moves air across the heat sinks to keep power components within their operating temperature range. This airflow method removes heat directly from the power section and avoids the need for external ducting around the module. The unit is part of Line 03, which identifies the third design line used for this platform and its connector layout.
The controller is Version 1, so its parameter structure and diagnostic code format follow the first release used for this model. It is classified as an HDS Drive Controller, which separates it from other controller types in the same product range. In multi-axis systems, it works with matching supply and feedback modules to support coordinated axis control across several channels. It is suitable for legacy automation platforms that rely on coordinated motion across several axes.
