Product Description:

The HDS03.2-W075N-HT11-01-FW is an axis drive controller produced by Bosch Rexroth Indramat as part of the HDS Drive Controllers series. Installed in a DIAX04 multi-axis rack, it regulates current, velocity, and position for servo motors that are coordinated by a higher-level motion system. Within an industrial cell, it closes the power loop between a central controller and a motor, translating low-level command data into controlled three-phase output to move a machine axis precisely. This operating role allows the controller to support accurate acceleration, steady running speed, and controlled stopping on automated axes.

This unit exchanges real-time motion data through the SERCOS fiber-optic interface, allowing deterministic synchronization with neighboring drives. A built-in air blower draws cabinet air through the heat sink, so the controller does not require an external fan for its own cooling. The power stage is rated for 75 A continuous output, giving adequate headroom for medium-to-large servo axes that demand high dynamic torque. The unit is Version 2, and it is intended for use where stable communication and continuous current delivery are required across repeated motion cycles.

The device is part of Line 03, so its front card guide, rear backplane, and address selector follow that rack standard and slot numbering. It is classified as an HDS Drive Controller and can be combined with supply modules and auxiliary cards from the same platform to build multi-axis systems. In this current class, the controller is intended for axes below the 100 A range, which places it between lower-power rack positions and larger cards used for heavier loads. Its rack-compatible format also allows it to sit beside matching system modules in a shared enclosure without changing the established card layout.
