Product Description:
The HDS04.2-W200N-HA21-01-FW drive controller is produced by Bosch Rexroth Indramat. As a digital servo amplifier, it regulates current and velocity loops for synchronous and induction motors in multi-axis machining centers, material-handling cells, and other industrial automation stations that require coordinated motion. In closed-loop operation, it converts DC-bus power into controlled motor current so the connected axis can follow commanded speed and torque. Encoder feedback is processed inside the controller to correct deviations caused by changing loads and rapid acceleration. This supports repeatable motion where several axes must start, stop, or change speed in a coordinated way.
The unit exchanges setpoints and status words through an analog command interface, so velocity or torque commands arrive as voltage levels rather than over a digital network. Continuous output capability is supported by a rated current of 200 A, which allows the power stage to supply high phase current during sustained operation. Thermal stability is maintained by a built-in air blower, which moves cabinet air across the heat sink instead of relying on external ducting. The controller is part of the DIAX04 family, so it matches the modular backplane and shared supply structure used across that platform. It is Version 2 and belongs to Line 04.
As an HDS Drive Controller, the unit follows the modular wiring approach used across this product line. Separate system modules provide items such as the shared power section and communication hardware, while the controller focuses on regulation at the axis level. This layout suits centralized cabinets where multiple axes share the same electrical infrastructure. It is part of the HDS Drive Controllers series, which uses a consistent module format for multi-axis drive systems.
