HDS03.1-W075N-HT05-01-FW
The HDS03.1-W075N-HT05-01-FW is a modular drive controller produced by Bosch Rexroth Indramat for the HDS Drive Controllers series. It occupies a single controller slot inside a multi-axis rack and provides the interface between a machine's motion commands and the connected power section. By converting control commands into regulated motor current, the unit supports accurate positioning, stable speed control, and coordinated axis movement in automated equipment. In automated cells, it regulates servo axes, closes velocity and position loops, and exchanges process data with the central PLC over fiber optics.
This controller communicates through the SERCOS real-time interface, so motion commands and parameter data are transferred in deterministic cycles that coordinate multiple drives on the same ring. This arrangement supports synchronized command execution and consistent feedback handling across linked axes. A rated output of 75 A supplies current for medium-power servo motors during acceleration and continuous load. Internal cooling air is circulated by a built-in air blower, which directs airflow across the heat sink without external ducting. The controller is part of the DIAX04 platform, so its diagnostics and connector layout match other modules used in the same rack.
The unit is Version 1. It is filed under Line 03, indicating mechanical dimensions that align with third-generation supply units and auxiliary modules. Its modular format allows it to operate alongside axis modules, supply sections, and interface cards in one drive assembly. The rack-based layout supports compact multi-axis installations and keeps the controller integrated with adjacent modules that use common spacing and shared optical communication. That arrangement keeps power, control, and interface sections organized within a common cabinet structure.
