Product Description:

The HDS04.2-W200N-HT29-01-FW is a drive controller produced by Bosch Rexroth Indramat and supplied in the HDS Drive Controllers series. It regulates power modules and feedback loops in multi-axis machining centers, presses, and material-handling cells where precise velocity and torque control are required. By converting setpoint data from higher-level motion systems into regulated current for connected servo and spindle amplifiers, the unit serves as a central control element in many rack-based drive systems. This role allows the controller to support coordinated motion on machines that depend on accurate speed regulation, repeatable torque response, and stable operation during changing loads. It is used where several axes share a rack and the control system must keep motion behavior consistent during feeding, forming, lifting, or transfer processes.

Communication is handled through the SERCOS optical interface, allowing deterministic command exchange between the controller and the motion CPU. Within the DIAX04 architecture, that link supports synchronized cycle times across multiple axes and reduces interface wiring inside the rack. Thermal management relies on a built-in air blower, so the cabinet does not require external ducting for routine cooling. The power section is rated for 200 A, which allows the controller to supply high transient and continuous current to demanding motor applications. That current capacity is suited to large servo and spindle axes that draw substantial torque during acceleration and process changes. The unit is part of Line 04, and it is built as Version 2.

The controller operates on a common DC bus, allowing regenerated energy from one axis to be shared with neighboring axes in the same system. In mixed racks, the standardized backplane supports installation with compatible modules across the platform without rewiring field connections. Integrated diagnostic status LEDs and serial telegrams report internal operating states, making it easier to monitor communication, cooling, and drive readiness during machine operation. Serial messages can be read by the control system for fault tracing and general status supervision while the machine remains in service. This arrangement supports clear status monitoring for rack assemblies that combine several coordinated axes in one drive system.
