Product Description:

The HDS03.1-W100N-HS84-01-FW is a drive controller produced by Bosch Rexroth Indramat and assigned to the HDS Drive Controllers series. In automated production lines, this unit forms the actuator side of a motion system by converting numerical setpoints from a supervisory controller into regulated motor currents. It acts as the power and control stage between the higher-level controller and the motor, supporting accurate response during acceleration, deceleration, and continuous operation. By coordinating torque, speed, and position loops, it enables precise operation of servo axes used in material handling, packaging, and general machinery.

During operation, the controller exchanges real-time data over the SERCOS bus, a deterministic fiber-optic network that conveys setpoints, feedback, and status data in synchronized cycles. Because the data stream is cyclic and predictable, axis commands and returned feedback remain closely coordinated during multi-axis motion. The module can supply up to 100 A of regulated output to the connected servo motor phases, supporting applications that require sustained current under industrial duty. Heat generated by switching losses is removed by a built-in air blower, which reduces reliance on external cabinet ventilation. The unit is part of the DIAX04 platform and belongs to Line 03, matching the mechanical slot pattern and backplane connectors used by companion supply units.

The unit is Version 1 for this model. It uses a command communication interface that matches the real-time motion bus, so command exchange remains consistent across the drive system. This keeps the communication structure straightforward in systems that already rely on the shared motion network for control traffic. It also allows the controller to operate within coordinated axis groups without adding a separate command path.
