Product Description:

The HDS03.2-W075N-HS26-01-FW is a modular drive controller produced by Bosch Rexroth Indramat. It operates as a servo axis module within multi-axis racks to regulate AC motors in automated machinery, presses, and transfer lines. By converting setpoint data from the host control system into controlled current and voltage patterns, the device closes the drive loop for position, speed, and torque tasks in industrial automation. In a rack-based system, the module handles the power conversion stage for one axis while the higher-level controller supplies motion commands and operating references. This arrangement supports coordinated movement where multiple machine axes must respond accurately during repeated production cycles.

The communication interface is SERCOS, allowing fiber-optic data exchange for real-time setpoints and feedback. A rated output of 75 A is the maximum continuous motor phase current the module can supply without thermal derating. Cooling is handled by an internal air blower, which moves air through the heat sink to keep semiconductor temperatures within a normal operating range. The controller belongs to the DIAX04 family, which uses common mechanical dimensions and backplane connections across axis modules. That common platform keeps neighboring modules in the same rack aligned with the same basic electrical and mounting format.

The product is part of Line 03 in the series. The drive is Version 2. The unit is an HDS Drive Controller. It works with HMU mains units and HVE supply sections in the HDS Drive Controllers series, allowing it to be integrated into coordinated multi-axis drive systems with shared supply components. This configuration places the controller in a cabinet-based drive platform where each axis module performs its own control function while operating from a common system structure.
