HDS03.2-W100N-HS24-01-FW
The HDS03.2-W100N-HS24-01-FW is a drive controller produced by Bosch Rexroth Indramat for the HDS Drive Controllers series. Within a multi-axis cabinet, it regulates torque, velocity, or position on coordinated servo motors, acting as the closed-loop element that converts CNC or PLC commands into phased current for each axis. By combining command processing, power electronics, and thermal management in one housing, the unit streamlines installation in automated machining cells, material-handling gantries, and packaging lines. It is used where several servo axes must coordinate their movement under a central motion controller.
The module exchanges motion data over the SERCOS fiber-optic bus, allowing synchronized operation across multiple axes and consistent command timing. During peak acceleration it can supply up to 100 A of output current, so the connected motor can reach commanded torque without external boosters. Heat generated by switching losses is removed by a built-in air blower, which circulates cabinet air across the heat sink and eliminates the need for ducted cooling. The controller belongs to the DIAX04 family, so it follows the mechanical format used in that platform. It is part of Line 03 in that platform, and fiber-optic communication also helps isolate the control link from electrical noise inside the cabinet.
This unit is Version 2. As an HDS Drive Controller, it serves as the power and regulation stage for a servo axis and works with compatible supply modules in the same cabinet. The control section, power stage, and cooling hardware are integrated into one enclosure, which helps keep cabinet layouts compact while supporting closed-loop motion control. This arrangement supports cabinet-based servo systems that require stable current regulation during repeated acceleration and deceleration. The revision marks a later design within the product line and retains the same basic role of processing axis commands, regulating motor current, and stabilizing speed or position during operation.
