Product Description:

The HDS04.1-W200N-HT13-01-FW belongs to the HDS Drive Controllers series from Bosch Rexroth Indramat. As a modular servo drive controller, it provides closed-loop regulation for multiple axes and integrates into the DIAX04 automation platform to coordinate motion tasks in machining centers, printing lines, and material-handling cells. It converts DC bus power into controlled motor output so the connected system can regulate torque, speed, and position during synchronized machine operation. In a drive cabinet, it works as the regulated power stage between the shared DC bus and the motor on each axis.

The unit exchanges setpoints and feedback through the high-speed SERCOS optical ring, a deterministic protocol that synchronizes drives and PLCs over a single fiber pair. Power electronics inside the controller are rated for a continuous output of 200 A, allowing operation of large synchronous or induction motors without derating under normal conditions. The hardware uses the mechanical Line 04 form factor, which keeps it consistent with related modules in the platform. Diagnostics use the same channel as the command communication interface, so no separate serial link is required. Because SERCOS exchanges cyclic data in real time, motion commands and returned feedback remain aligned during coordinated movement.

Cooling is handled by a built-in air blower that directs airflow through the IGBT heat sink, so no external fan tray is required. The airflow path removes heat from the power semiconductors during sustained current delivery and helps maintain stable thermal conditions inside the housing. The product is Version 1. Within the DIAX product hierarchy, it is part of the DIAX04 controller family, which allows it to share backplane connections and parameter structures used across that platform. Functionally, the module is designated as an HDS Drive Controller, placing it in the power section of the motion system where it converts DC bus energy into three-phase motor voltages while maintaining axis-specific torque, speed, and position limits.
