Product Description:

The HDS04.2-W200N-HS74-02-FW is a modular controller in the HDS Drive Controllers series developed by Bosch Rexroth Indramat. Within an automated machine, it regulates torque, speed, and position of connected AC servo drives and closes the motion loop through a fiber-optic network. By coordinating multiple axes from a shared power supply, the unit supports compact cabinet layouts and synchronized motion sequences in packaging, material-handling, and machining cells. It is intended for drive cabinets where coordinated servo motion and centralized power architecture are needed.

This controller exchanges setpoints and feedback over the SERCOS serial real-time bus, allowing deterministic command cycles and standardized telegrams for drive, I/O, and sensor data. It belongs to the DIAX04 family, so its form factor and parameter structure match other DIAX modules used in the same platform. The power stage is rated for 200 A continuous output, which supports large servo axes and requires appropriate cable sizing and cabinet cooling. A built-in air blower moves cooling air through the heat-sink channels, eliminating the need for external fans or liquid loops while keeping component temperatures within safe operating limits. Consistent communication timing helps the controller exchange motion data with the higher-level control system without irregular cycle delays. The product is part of Line 04.

The unit is Version 2, which indicates the current product revision for this ordering code. It mounts in a shared bus bar system, allowing energy recovery and common DC distribution among axes in the same drive assembly. Shared DC distribution allows several axes to use the same DC source instead of separate power conversion stages. Energy recovered during deceleration can be made available on the shared bus when other connected axes are accelerating.
