Product Description:

The HDS03.2-W075N-HS45-01-FW is a drive controller manufactured by Bosch Rexroth Indramat and supplied in the HDS Drive Controllers series. Installed in a DIAX04 rack, it forms one controlled axis within a shared DC-bus system. It receives power from the system supply module and modulates that energy for a connected motor axis. In automated equipment, this allows the controller to carry out commanded acceleration, holding, and speed changes with repeatable timing. Such operation is useful in palletizers, pick-and-place units, and machine tools where coordinated motion must remain stable through repeated cycles.

The controller can deliver up to 75 A, which gives it the current capacity needed for medium-frame motors under sustained load. Command data are exchanged through the SERCOS interface, a fiber-optic link that provides deterministic real-time communication and returns axis feedback with strong resistance to electrical noise. The unit belongs to Line 03, which places it in the third layout generation used within this product platform and keeps the connector and mounting arrangement consistent within that line. Cooling is handled by a built-in air blower that moves cabinet air across the power section, so no liquid cooling hardware is required. This airflow helps the module maintain stable thermal conditions during extended operation.

It is intended to regulate a servo or main spindle motor and is listed as Version 2. Its modular format allows it to occupy a defined position in a multi-axis assembly while sharing DC-bus power with neighboring drive units. During operation, it converts incoming DC energy into controlled motor output so the connected axis can respond accurately to torque, speed, and position commands. It works in rack-based systems where multiple axes operate from the same power structure.
