Product Description:

The HDS05.2-W300N-HT11-01-FW is a modular drive controller manufactured by Bosch Rexroth Indramat for the HDS series. In industrial automation, it links the central motion processor and the motor power stage, supplying regulated three-phase energy so connected servo axes can follow precise velocity and position commands from the higher-level control. By integrating control electronics and cooling hardware into one housing, the module streamlines cabinet layouts and reduces the number of external components used on multi-axis gantries, presses, and machining centers.

The command layer is handled through the SERCOS fiber-optic loop, allowing deterministic transfer of setpoints, feedback, and diagnostic data without a separate fieldbus adapter. Electrically, the unit belongs to the DIAX04 controller family and has a continuous output capability of 300 A, which suits large torque motors and rapid-acceleration axes. Thermal management relies on a built-in air blower; the integral fan draws cabinet air across the heat-sink fins instead of requiring external ducting or liquid cooling. Each controller operates from a shared DC bus, so regenerated energy from one axis can be redistributed to another axis in the system.

The unit is a Version 2 build in Line 05 of the design sequence. It is classified as an HDS Drive Controller, so it serves as the main control section for coordinated servo motion within the drive system. The module combines current regulation and command handling in one housing, reducing the need for separate control hardware at the axis level. This arrangement supports synchronized motion in applications where multiple axes must respond to tightly timed command updates and stable current delivery under changing loads. It also supports high-power servo applications that require repeatable motion across several coordinated axes.
