Product Description:

The HDS04.1-W200N-HS23-01-FW is a drive controller built by Bosch Rexroth Indramat for the HDS Drive Controllers series. Integrated into multi-axis automation racks, the unit converts centralized motion commands into regulated current for power sections that actuate servo motors. It serves as the control stage between the rack supply structure and the connected axis, so commanded torque and speed can be regulated with repeatable response. By regulating current rather than passing raw line power, it gives the axis precise electrical control during acceleration, holding, and speed changes.

This controller supplies up to 200 A of continuous output, which suits axes that draw high peak torque without derating during sustained operation. Thermal stability is maintained by a built-in air blower; it moves cabinet air across the heat sink so additional external cooling hardware is not required. Command data reaches the module through the fiber-optic SERCOS interface, providing deterministic cycle timing and galvanic isolation from drive power electronics. The unit belongs to the DIAX04 family, so it uses the same backplane arrangement and connector layout as related axes in that range. Because cooling is handled inside the module, cabinet airflow can be directed across the rack without separate fan assemblies for each axis.

The designation Line 04 places the controller in the fourth design line, so connector pinouts and housing dimensions match that generation’s power supplies. The unit is marked as Version 1, which identifies the revision used for this controller and keeps the type code easy to interpret. The product is categorized as an HDS Drive Controller, indicating closed-loop current and velocity regulation rather than open-loop power amplification. That role fits a rack system in which the controller manages motor response while working with the centralized power structure used by the series.
