HDS03.1-W075N-HA04-01-FW
The HDS03.1-W075N-HA04-01-FW is an HDS Drive Controller from Bosch Rexroth Indramat and belongs to the HDS Drive Controllers series. Installed in modular automation racks, the unit converts motion commands into regulated three-phase motor power while monitoring current, voltage, and temperature limits. It forms the link between a motion PLC and the mechanical drive train, supporting precise positioning and repeatable cycle times in packaging machines, machining centers, and material-handling cells. Its control and power functions are combined in one housing, which helps the axis respond consistently during speed changes and position corrections.
The controller has a current rating of 75 A, allowing it to power medium-duty servo motors during acceleration and braking. Commands are received through an analog command interface, so reference values from the PLC are transmitted as ±10 V signals and converted into pulse-width-modulated drive output. Thermal management is handled by a built-in air blower that moves air across the heat sink and supports continuous operation without external cooling hardware. As part of the DIAX04 platform, the unit can be used in synchronized multi-axis applications such as electronic gearing and camming. This setup supports coordinated motion between neighboring axes in a shared drive system.
The device is part of Line 03, which uses common backplane geometry and connector pinouts for this design line. It is supplied as Version 1, identifying the product generation for this controller. The housing is intended for installation in modular racks, where the power section and control section operate together in a compact drive assembly. This layout allows the unit to integrate with matching system modules while keeping wiring paths short inside the cabinet.
