HDS04.1-W200N-HT10-01-FW
The HDS04.1-W200N-HT10-01-FW is a digital drive controller from Bosch Rexroth Indramat and is assigned to the HDS Drive Controllers series. Designed for installation in a multi-axis rack, the unit converts motion commands from a higher-level control into regulated three-phase power for servo motors used in material handling systems, machining centers, and similar industrial equipment. It serves as the link between the control platform and the motor power section, translating requested motion into controlled electrical output. In automated lines, this supports coordinated motion where multiple drives operate from a central control system.
Communication with the motion system is handled through the SERCOS fiber-optic interface, which carries position, velocity, and diagnostic data in real time. The module belongs to the DIAX04 family and is part of Line 04, so its mechanical footprint and backplane connections match companion supply and control units in the same platform. This layout keeps the controller compatible with rack-based assemblies that use common module spacing and shared internal connections. Real-time data exchange through the optical link helps the control system monitor axis behavior and respond quickly to operating changes.
Thermal dissipation relies on a built-in air blower that moves cabinet air across the heat sink, so no external ducting is required. The power stage supports a continuous output of 200 A, which allows direct operation of large synchronous or asynchronous servo motors without a supplemental amplifier. The unit is identified as Version 1, indicating the initial release for this controller type. Internal airflow helps remove heat from the power components during sustained operation, which is important when the controller is driving high-load axes in a compact cabinet layout.
