Product Description:

The HDS03.2-W100N-HT27-01-FW is a drive controller manufactured by Bosch Rexroth Indramat and assigned to the HDS Drive Controllers series. Designed for servo axes in automated machinery, the unit converts motion commands into controlled current for synchronous and induction motors. By coordinating drive tasks with the higher-level PLC through the series back-plane, it supports multi-axis assemblies that require accurate torque and speed regulation. Because it handles motor current directly, the controller bridges command processing and power conversion within one module. This role fits machines that rely on tightly timed axis motion instead of isolated motor operation.

Motion data reaches the controller through the SERCOS real-time bus, so the axis can be synchronized with other nodes in the system. That connection supports deterministic command updates and feedback exchange during coordinated moves. Inside the DIAX04 rack, the unit is part of Line 03. The power stage is rated for a continuous output of 100 A, supplying enough current for medium-to-large motors in demanding servo applications. Thermal energy is removed by a built-in air blower, which draws cabinet air across the heat sink instead of requiring separate ducting. This cooling method supports stable operation during repeated load changes and sustained current demand.

The controller is Version 2, which identifies the release level of this unit. Its command interface works with the control system to manage acceleration limits, current-loop settings, and alarm responses during operation. Those settings help the axis respond consistently when commanded speed or torque changes during a cycle. The control exchange keeps the drive aligned with the rack-based system architecture while allowing the axis to react quickly to changing demand. The rack-based architecture keeps control signals and power handling in the same coordinated system.
