Product Description:

The HDS03.2-W100N-HS75-01-FW is a drive controller from Bosch Rexroth Indramat in the HDS Drive Controllers series. It serves as the regulated power stage for servo axes and interfaces with rack-based automation systems that use a shared DC bus. The unit converts incoming DC bus energy into controlled three-phase motor output so the connected axis can maintain commanded speed and torque during operation. It also links motion commands with the motor feedback loop and supervises protective functions needed for closed-loop positioning. Inside an industrial cell, it supports precise current regulation for repeatable movement in automated machinery.

As an HDS Drive Controller, the unit exchanges cyclic command data through the fiber-optic SERCOS interface for synchronized motion control. It is intended for the DIAX04 platform, so it fits the corresponding rack architecture and works with the related auxiliary connections used in that system. Fiber-optic communication helps the controller operate in step with other motion nodes on the same network. The controller can deliver a continuous output of 100 A, which supports high-inertia axes during sustained motion as well as repeated acceleration and deceleration. Its class designation separates it from spindle-oriented modules that may be mounted in the same overall rack family.

Cooling is handled by a built-in air blower that moves cabinet air across the heat sink and helps keep internal temperatures stable during operation. Because the airflow device is integrated into the unit, external ductwork is not required for normal heat removal within a properly ventilated cabinet. The controller is part of Line 03, and it is marked as Version 2. These identifiers indicate the product generation used for this controller and distinguish it from earlier revisions in the same product line. The blower uses cabinet air rather than a separate external cooling circuit.
