HDS03.2-W100N-HS94-01-FW
The HDS03.2-W100N-HS94-01-FW drive controller is produced by Bosch Rexroth Indramat for the HDS Drive Controllers series. It installs in a multi-axis cabinet and produces three-phase output currents that track commanded setpoints, allowing servo motors to accelerate, hold speed, or decelerate under precise electronic supervision. In automated packaging, material-handling, or machining cells, the device functions as the interface between the machine control program and the physical motion hardware, translating digital commands into regulated electrical power. During operation, the controller regulates motor current in response to incoming commands so axis motion remains stable during speed changes and load transitions.
Control data reach the unit through the SERCOS fiber-optic ring, which supplies synchronized cyclic setpoints and status words without separate analog wiring. Because the controller belongs to the DIAX04 family, it shares a common connector layout with other axes in the same rack and fits established cabinet architectures for that platform. Heat generated by the power transistors is removed by a built-in air blower, so no external ducting is required inside the cabinet. The power stage is rated for a continuous motor current of 100 A, making it suitable for high-torque applications. The unit is part of Line 03, which identifies the design line used for this model.
The unit is Version 2, which indicates the second electrical revision of the control board. It contains its own power electronics and blower assembly, so the controller operates as a self-contained drive module within the rack. This layout supports closed-loop motor control without separate external cooling hardware for the controller body, and it keeps the installation centered on the shared cabinet power and communication structure. The integrated arrangement also keeps the current-control section and its cooling path within the same enclosure.
