Product Description:

Bosch Rexroth Indramat manufactures the HDS03.2-W075N-HT01-01-FW drive controller as part of the HDS Drive Controllers series. The unit regulates torque, speed, and position loops for servo axes, acting as the power and control interface between the DIAX04 automation platform and the machine's motion hardware. In multi-axis cabinets, it supplies regulated DC-bus energy and executes closed-loop commands so connected motors follow programmed trajectories in packaging, printing, and material-handling equipment. This operating role allows the controller to support repeatable motion on axes that must start, stop, and synchronize without drifting from commanded values.

Electrical delivery is centered on a rated output of 75 A, giving the axis module enough current for acceleration and synchronized operation. Control commands reach the device through the SERCOS fiber-optic interface, so real-time setpoints, diagnostics, and parameter data move in a deterministic cycle with neighboring drives. Because the link is optical, communication is less affected by electrical noise from nearby power components inside the cabinet. The controller belongs to the DIAX04 family, and thermal regulation relies on a built-in air blower that draws cabinet air across the heat sink to control internal temperature. The unit is Version 2, indicating the second revision for this controller type.

The product is part of Line 03, which places it in the third design line of the series. Its dimensions and connector positions match modules of the same line, so it can mount in a compatible backplane without custom brackets. This layout keeps power, feedback, and control connections at predictable locations inside dense control cabinets. Front access to these connections helps maintain orderly cable routing where several axes are installed side by side.
