HDS03.1-W075N-HS38-01-FW
The HDS03.1-W075N-HS38-01-FW is a drive controller built for the HDS Drive Controllers series by Bosch Rexroth Indramat. It serves as the regulating core of a multi-axis motion rack in automated machining, packaging, or material-handling lines. The controller converts high-level trajectory commands from the machine PLC into precise current, velocity, and position references for connected servo or spindle drives. That role lets the rack coordinate multiple axes while preserving the response needed for contouring, indexing, and speed-regulated spindle tasks.
Command data is exchanged through the SERCOS fiber-optic interface, which supports cyclic telegrams so axis interpolation remains synchronized across the rack. Because communication is optical, the interface resists electrical noise that is common around switching power electronics. The module is part of the DIAX04 family, which gives it a compatible back-plane pinout and parameter structure with companion power sections. A continuous load rating of 75 A allows the unit to modulate substantial phase current for demanding servo axes. This current capacity supports sustained torque demand on larger motors without immediate thermal derating during continuous operation. Heat is removed by a built-in air blower, so the controller can manage internal thermal loading without external ventilation hardware. The unit is part of Line 03 in the product range.
The unit is classified as an HDS Drive Controller, so motion-control logic, communication handling, and gating signals are contained on one board rather than being distributed across separate modules. The product is Version 1. This arrangement keeps command processing and regulation within the same controller, which suits multi-axis racks that separate the control stage from the power stage. In a modular system, this helps centralize communication and control functions while separate power hardware supplies the motor current path.
