Product Description:

The HDS04.1-W200N-HT23-01-FW is a drive controller produced by Bosch Rexroth Indramat in the HDS Drive Controllers series. Installed in a modular cabinet, it connects the shared DC bus to individual servo axes and forwards real-time command data between the motion control system and the motor power stage. In industrial automation, it converts three-phase supply power into tightly timed current pulses so attached motors can follow programmed position, speed, and torque profiles in machining centers, press lines, and material-handling systems. In a multi-axis cabinet, the unit serves as the interface between the supply section and the servo axis, allowing commanded acceleration, holding torque, and speed changes to be carried out with precise timing.

Communication with the motion coordinator is handled through the optical SERCOS interface, giving deterministic cycle times and simple fiber routing between modules. This optical link supports synchronized command exchange across the drive group without adding electrical noise from copper communication wiring. Thermal regulation is provided by a built-in air blower, which removes the need for external ductwork inside the control cabinet. The power section can continuously supply up to 200 A, and this value is the controller's rated current, so connected cables and protective devices must match it. The unit is version 1.

Within the DIAX04 platform, the device belongs to Line 04, placing it in the fourth design line for this series. Its line assignment keeps addressing and configuration data consistent with neighboring modules, which is important in racks where several axes share one supply section. The module uses standardized bus connectors and cabinet dimensions so it can be installed alongside matching supply and terminator modules on the same rail. It is intended for coordinated servo applications that rely on fast update rates across several axes during contouring, transfer, or press sequences.
