Product Description:

The HDS03.2-W075N-HS94-01-FW is a drive controller developed by Bosch Rexroth Indramat. As a modular axis controller, it supplies regulated power to servo drives and coordinates motion commands in multi-axis industrial machinery. The unit belongs to the DIAX04 automation platform, so it integrates into cabinet racks where multiple drives share a common supply. In production lines, packaging systems, and machine tools, the device receives digital motion data, modulates output current, and helps each connected motor follow its programmed profile with tight speed and position accuracy. Because it operates in a shared control environment, it supports coordinated axis behavior across machines that need repeatable motion from several motors at once.

Its communication interface is the SERCOS fiber-optic bus, which allows cyclic setpoint exchange and diagnostic feedback with deterministic timing for synchronized axes. The controller is part of the DIAX04 family, so its backplane connectors match the shared supply and I/O modules used in that platform. During operation, the power stage can deliver a continuous output of 75 A, so connected components must be rated for that current during peak load cycles. Thermal management is handled by a built-in air blower that draws air through the heat sink and expels it into the cabinet to help prevent derating. The model is part of Line 03, which indicates the mechanical layout and connector arrangement inside the drive stack.

The unit is Version 2. It remains classified as an HDS Drive Controller, so the mounting holes, terminal locations, and parameter structure follow the layout used across the HDS Drive Controllers series. Within a shared-rack installation, this format helps the controller fit alongside compatible supply and interface modules without changing its intended role in axis control. The arrangement also supports orderly integration in multi-axis cabinets where several modules work together from the same platform.
