Product Description:

The HDS04.2-W200N-HT70-01-FW is a modular drive controller produced by Bosch Rexroth Indramat and supplied within the HDS Drive Controllers series. It acts as the power and regulation stage between a central motion processor and synchronous servomotors, shaping motor current, monitoring feedback, and executing real-time diagnostics for coordinated axis movement in packaging, printing, and metal-cutting equipment. That arrangement lets the controller respond quickly to command changes while supporting regulated torque and speed. It is intended for applications that require repeatable axis response during frequent starts, stops, and speed changes. Its housing places power semiconductors, control logic, and protective circuits on one frame, which helps reduce panel depth in multi-axis cabinets.

This controller exchanges cyclic setpoint, status, and parameter data over SERCOS, a deterministic fiber-optic bus used for multi-axis synchronization. Its power section delivers up to 200 A of continuous output, allowing high-inertia loads to accelerate without derating. Thermal limits are managed by a built-in air blower that directs airflow across finned heat sinks instead of relying only on cabinet ventilation. The device is part of the DIAX04 automation family. The unit is Version 2 and supports higher-resolution encoder operation for tighter speed control and improved monitoring during closed-loop motion.

Inside a DIAX rack, the controller occupies the address range marked as Line 04, which helps keep module order clear in multi-axis layouts. It connects through a common backplane that carries DC link voltage and communication channels between adjoining modules. This layout supports rack-based assemblies where power and communication are distributed through adjacent modules instead of separate point-to-point wiring. Integration with servo drives, power supplies, and I/O units remains consistent because the platform uses shared diagnostics, parameter names, and connector pinouts across the drive system.
