HDS05.2-W300N-HS25-01-FW
The HDS05.2-W300N-HS25-01-FW is a drive controller built by Bosch Rexroth Indramat and placed in the HDS Drive Controllers series. In a multi-axis drive system, the unit functions as the command and power stage between the supply module and connected servo drives, converting DC bus energy into controlled armature current while relaying velocity or position commands. It is used where a central supply module feeds several servo axes and where coordinated motion must be maintained during continuous machine operation. By combining these functions in one housing, it supports high-power motion axes used in machine tools, printing lines, material-handling cells, and other automated equipment.
The controller delivers a continuous output of 300 A, which suits demanding axes that require sustained current under load. Thermal management is handled by a built-in air blower, and the fan pulls cabinet air across the heat sinks so no external ducting is required. Fiber-optic SERCOS links carry cyclic setpoints and real-time diagnostics, helping maintain synchronized communication across multiple axes in the same installation. The unit is part of the DIAX04 controller family, so its parameter structure and diagnostic behavior follow that platform. Optical communication also helps avoid electrical ground loops between linked axes.
The drive is Version 2 and part of Line 05. It combines power electronics and control logic on a single frame, which reduces the number of separate modules needed for an axis. The layout matches the modular busbar arrangement used in this product range, allowing direct integration with adjacent system components. Because current conversion and motion command handling are contained in one controller, the unit fits installations that require coordinated operation across several servo axes. The single-frame design also helps keep cabinet layouts orderly when high-current drive sections are grouped closely together in shared enclosures.
