HDS03.1-W075N-HA03-01-FW
The HDS03.1-W075N-HA03-01-FW is an industrial drive controller produced by Bosch Rexroth Indramat for the HDS Drive Controllers series. Installed in DIAX04 multi-axis cabinets, the unit delivers regulated drive power and motion commands to servo and spindle axes, allowing machine tools, printing presses, and handling equipment to execute coordinated moves. It serves as the axis interface that converts reference signals from a supervisory PLC into precise current control while monitoring motor feedback for stable, repeatable motion in automated lines. In continuous production service, this helps each connected axis respond quickly to changing speed or torque demands from the machine controller.
At the power stage, the controller supplies up to 75 A of continuous output current, enabling medium-to-large synchronous or asynchronous motors to run without derating. Control references enter through an analog command interface, so ±10 V velocity or torque signals from legacy or modern PLC cards can be accepted without protocol conversion. Thermal management is handled by a built-in air blower; the fan draws cabinet air through the heat sink to keep semiconductor temperatures within limits. The unit belongs to the DIAX04 family, which supports shared power buses and communication backplanes in that platform. The unit is part of Line 03, which uses the mechanical dimensions and connector layout found on other third-line HDS modules.
The unit is Version 1. Its diagnostic structure and parameter layout follow the HDS platform, which keeps operating data and status information organized in a familiar format across the cabinet. The controller combines power electronics and axis control logic in one housing, reducing the number of separate modules needed for an axis channel. This layout also keeps wiring paths short between the control section and the output stage.
