Product Description:

The Bosch Rexroth Indramat HDS04.2-W200N-HS87-01-FW is a modular axis drive unit in the HDS Drive Controllers series. As an HDS drive controller, it regulates power flow from the supply module to individual servo axes in multi-axis DIAX systems. This modular format allows a shared supply section to support several axis controllers in one cabinet while each controller remains dedicated to its assigned motor. In automated assembly lines and machining centers, the unit works with digital servo modules to coordinate velocity, torque, and position while maintaining cycle precision.

Command exchange relies on the SERCOS optical ring, allowing deterministic communication between the drive and CNC or PLC hosts. Within the DIAX04 family, the controller supports high-speed interpolation for coordinated axis motion during contouring and positioning tasks. The power section is rated for 200 A, so it can operate large synchronous or induction motors without current derating under nominal line voltage. Thermal management is handled by a built-in air blower that pulls cabinet air through the heat sink fins, so no external heat exchanger is required. This airflow arrangement helps remove internally generated heat during sustained high-current operation.

In the DIAX modular scheme, the controller is part of Line 04, which uses the same card size and backplane pinout across servo axes of the same generation. The unit is Version 2, and it supports extended diagnostic telegrams together with quicker axis enable sequences than the initial release. It also uses consistent encoder evaluation rules and fault word structures within the same rack, which helps keep multi-axis behavior uniform during operation. These characteristics are useful when several coordinated axes share the same cabinet architecture and communication cycle.
