HDS03.2-W100N-HT19-01-FW
The HDS03.2-W100N-HT19-01-FW is a modular drive controller manufactured by Bosch Rexroth Indramat for the HDS Drive Controllers series. In multi-axis drive stacks, it converts motion commands from CNC or PLC systems into regulated current for servo axes. By controlling current in real time, it supports synchronized position and speed on automated machining, packaging, and material-handling equipment. The controller is used where multiple axes must remain coordinated during changes in speed, load, and commanded position.
The controller exchanges control data over a SERCOS fiber-optic link, allowing deterministic high-speed communication with upstream motion processors. The fiber-optic interface supports precise timing between the controller and higher-level motion hardware, which is important in synchronized axis groups. Its power section is rated for a continuous output of 100 A, which supports demanding acceleration and deceleration cycles on appropriately matched axes. Cooling is provided by a built-in air blower, which removes heat from the power electronics and helps the module operate reliably in enclosed cabinets. The unit is part of the DIAX04 architecture, so it uses the common mechanical format and module arrangement found across that platform.
The product is part of Line 03, which places it within the third design line of this controller range. It is identified as an HDS Drive Controller, so its main function is closed-loop current regulation rather than generating the shared DC bus supply for the system. Separate supply modules provide that DC bus power for the connected axes, which keeps the controller focused on axis regulation. The hardware is listed as Version 2, indicating the second revision of this model. This revision marks the updated build used for this controller type.
