Product Description:

The HDS03.1-W100N-HT11-01-FW is a drive controller produced by Bosch Rexroth Indramat within the HDS Drive Controllers series. The unit modulates power to multiple servo axes, executes motion commands, and exchanges real-time data with higher-level automation hardware. In factory lines, packaging cells, and material-handling stations, it supplies controlled three-phase output to synchronous or asynchronous motors. This allows connected axes to start, stop, index, and track commanded motion profiles while the controller regulates position, velocity, and torque in real time. It is suited for coordinated motion tasks where several machine functions must respond quickly to commands from a PLC or CNC.

At the power stage, the controller provides a continuous current of 100 A, allowing it to energize medium-to-large servo modules without external boosters. Communication with the motion PLC is handled through the SERCOS fiber-optic ring, enabling deterministic cycle times and reliable closed-loop updates. The fiber-optic link supports synchronized command exchange between the controller and the higher-level motion system, which is important for multi-axis timing. Because the device belongs to the DIAX04 family, it shares backplane connectors and supply modules with other axis units from that platform, which keeps module integration consistent inside a common rack. Thermal energy generated by the IGBT bridge is removed by a built-in air blower, so no additional heat sink ducts are required in the enclosure. As an HDS drive controller, the unit combines regulated power electronics and axis logic in a single housing.

The designation Line 03 places the unit in the third design line of the product range. Hardware Version 1 identifies the initial board revision used for this controller. Protective functions include temperature shutdown and short-circuit supervision, helping protect the power section during fault conditions and abnormal load events. The protective circuits monitor operating conditions and can stop the output stage when limits are exceeded. The housing also uses the standard mounting rails and connector locations used across the series, which supports consistent installation in multi-axis cabinets and control enclosures.
