Product Description:

The HDS04.1-W200N-HS04-02-FW is a drive controller produced by Bosch Rexroth Indramat for modular multi-axis systems that use digital feedback loops. It belongs to the HDS Drive Controllers series and coordinates power modules, feedback devices, and fieldbus networks so a servo axis can follow commanded torque, speed, or position references. Within an automation cell, the unit closes the drive loop and supplies regulated current to motors while exchanging status data with higher-level control hardware. This makes it suitable for servo applications that require coordinated motion, stable current control, and direct integration with rack-based drive assemblies.

The controller is part of the DIAX04 family and exchanges command and feedback telegrams over the optical SERCOS interface. This link provides deterministic cycle times and galvanic isolation between the drive and the CNC or PLC, which helps preserve signal integrity in electrically noisy machine environments. Motor phase current is regulated up to a continuous 200 A, so the unit can support large servo motors and demanding acceleration profiles. Internal components are cooled by a built-in air blower that directs airflow across the heat sinks without external cabinet fans or water lines, keeping the cooling arrangement contained within the controller.

The unit fits mechanically and electrically into the modular rack used by this product line, and the designation Line 04 matches its connector placement, housing depth, and mounting points to other fourth-line DIAX modules. The controller is Version 1, which supports first-generation SERCOS cycle structures used by this model and aligns its operating behavior with the intended control architecture. It is classified as an HDS Drive Controller and serves as a dedicated axis channel in multi-axis systems. The combination of rack compatibility, optical communication, and integrated airflow supports installation in cabinets built around modular servo platforms.
