HDS03.1-W075N-HS92-01-FW
The HDS03.1-W075N-HS92-01-FW drive controller is manufactured by Bosch Rexroth Indramat and belongs to the HDS Drive Controllers series. It is designed to regulate three-phase servo and spindle axes in modular motion systems. In automated equipment, it converts commands from a numerical control or other higher-level automation system into controlled motor current and velocity profiles. The controller regulates drive behavior in real time so the connected motor can follow commanded torque and speed changes with predictable response. This supports precise positioning, stable speed control, and coordinated multi-axis movement in machine tools and similar industrial applications.
Communication with higher-level controls takes place over the SERCOS fiber-optic bus, which provides deterministic cycle timing and standardized telegram exchange. That communication method supports synchronized command updates and consistent motion response across linked axes. The power section can deliver a continuous output of 75 A before protective derating begins. Thermal energy from the IGBT bridge is removed by a built-in air blower, so the cabinet only needs normal ambient air exchange instead of liquid cooling. The unit is part of Line 03, which identifies the third mechanical frame in the family and indicates the corresponding mounting hole pattern, connector layout, and overall height.
The controller belongs to the DIAX04 family of modular inverters and can slide onto a common DC bus rail with supply and auxiliary modules for shared regeneration. The unit is Version 1. Within a drive system, it serves as the power stage and closed-loop regulator between higher-level automation and the connected electric drives. The module works with the platform bus structure used in the family, allowing it to operate alongside supply and auxiliary units in the same rack arrangement. This role places current regulation and axis response directly inside the drive assembly rather than in an external control stage.
