Product Description:

The HDS04.2-W200N-HT12-01-FW is a drive controller produced by Bosch Rexroth Indramat and assigned to the HDS Drive Controllers series. In an automation rack, it converts DC bus power into a controlled three-phase output and processes motion commands so that servo axes follow precise position, speed, or torque profiles. By closing the drive loop at the module level, it reduces processing demand on the machine control while maintaining deterministic response. This arrangement lets the controller regulate motor current directly inside the drive system, which supports stable axis behavior during frequent speed and load changes.

Inside the controller, the communication port uses the SERCOS real-time network, allowing synchronized data exchange with a master over fiber. The device belongs to the DIAX04 controller family and is part of Line 04, so it shares mechanical dimensions and backplane pinouts with other members of that line. A built-in air blower moves cooling air across the heat sinks, letting the unit deliver its continuous output without external cabinet fans. The power stage is rated for 200 A, giving the module the capacity to run high-torque servo motors or parallel axes that require large short-term currents during acceleration. Because command data is exchanged in fixed cycles, coordinated axes can remain synchronized during interpolation, indexing, and rapid speed changes. Parameter storage, diagnostic indicators, and plug-in bus connectors are arranged on the front panel, while the rear edge connector links the controller to shared DC power.

The module is released as Version 2. Its fiber-optic link provides galvanic isolation from electrical noise, which helps preserve communication quality when the cabinet contains high-power switching devices. Optical signaling also avoids direct electrical coupling between the control master and the power electronics. The front-panel layout keeps status points and connectors accessible, and the rear connection supports integration with the shared power section of the rack.
