Product Description:

The HDS04.2-W200N-HS23-01-FW is a drive controller produced by Bosch Rexroth Indramat as part of the HDS Drive Controllers series. Designed for installation in an automation rack, it delivers closed-loop regulation for servo axes used in industrial robotics, metal-cutting machines, and high-speed handling equipment. The module interprets digital position or velocity commands and modulates DC-bus energy into phase-accurate motor current, providing the electrical interface between central motion planning and the mechanical load. This role allows the controller to support accurate speed changes and repeatable axis motion during automated production cycles. Because it works between the motion controller and the motor, it serves as both the power conversion stage and the regulation stage for commanded axis movement.

This controller exchanges real-time parameters through the optical SERCOS interface, allowing synchronous networking with drives and PLCs over a single fiber ring. Its output stage is rated for a continuous current of 200 A, so compatible motors can accelerate quickly without exceeding thermal limits. Heat is removed by a built-in air blower that circulates air along the heat sink fins without external ducting. The unit belongs to the DIAX04 controller family, which uses a standardized connector layout across the rack. The unit is Version 2 and includes updated gate drivers and monitoring circuits.

Within the type code, the line designator 04 matches 50 mm module spacing in the rack, which simplifies mixed-axis installation. This spacing keeps the front profile consistent across neighboring modules and helps maintain an orderly cabinet layout when several axes are installed side by side. The rack-based format also supports dense drive assemblies without changing slot width from one module position to the next. That arrangement is useful in cabinets where multiple drive modules must be grouped closely while still preserving accessible front connections. The controller is intended for servo systems that rely on coordinated command updates and stable current delivery during continuous operation.
