HDS03.1-W075N-HA17-01-FW
The HDS03.1-W075N-HA17-01-FW is a drive controller manufactured by Bosch Rexroth Indramat for the HDS Drive Controllers series of modular motion products. Installed beside intelligent power modules, it governs three-phase servo motors in machining cells, handling lines, and printing equipment. In this role, it converts supplied electrical energy into controlled motor output so the connected axis can respond accurately to changing command values during operation. It provides closed-loop speed and torque regulation where precise axis response is required.
This unit is identified within the controller family as DIAX04, so it mates electrically and mechanically with other DIAX04 assemblies in a common rack. Reference values arrive through an analog command interface that accepts standard ±10 V signals from a PLC or process computer. This interface suits control systems that send speed or torque references as continuous voltage commands rather than through a digital fieldbus. The power stage can supply up to 75 A of continuous motor current, which is an important value for conductor sizing and protective device selection. A built-in air blower moves cabinet air across the heatsink and maintains component temperature without external ducting. The unit is part of Line 03, which aligns diagnostic messaging and parameter structure with other third-generation devices in the same family.
The product is classified as an HDS Drive Controller, so axis control, monitoring, and protective shutdown functions are integrated into one card set. These functions allow the controller to supervise operating status and react to fault conditions inside the drive assembly. The unit is Version 1, indicating the first release used with this line. As part of the HDS Drive Controllers platform, it uses standardized backplane connectors and parameter files for integration in matching DIAX04 racks. Standardized connections also help keep rack wiring orderly when several axes are installed in the same cabinet.
