HDS03.2-W075N-HS28-01-FW
The HDS03.2-W075N-HS28-01-FW is a drive controller produced by Bosch Rexroth Indramat for the HDS Drive Controllers series. In a DIAX04 automation rack, it regulates servo and spindle axes by converting motion commands into controlled current and voltage for the connected motor system. This allows factory equipment such as handling robots, process tools, and production machines to coordinate position, speed, and torque through closed-loop control. The unit is intended for multi-axis applications where reliable digital communication and consistent axis response are required during continuous operation.
Motion data reaches the unit over the SERCOS fiber-optic ring, allowing deterministic exchange with CNC or PLC platforms. The power stage can source 75 A continuously, which supports axis loads that require sustained current without immediate derating. Heat is removed by a built-in air blower, which moves cabinet air across the heat sink to support stable thermal operation. The controller is part of the DIAX04 platform, and it is assigned to Line 03 within that product range. This layout helps keep electrical and mechanical integration consistent across related modules used in the same rack.
The unit is built as Version 2, identifying its product revision within this model line. As an HDS Drive Controller, it includes gating logic, diagnostics, and protective shutdown circuits inside the module rather than relying on external control hardware for those core functions. That arrangement reduces the number of separate control elements needed around the axis channel while keeping the drive ready to work with the required power module and feedback connections. Its modular format also supports organized rack installation, with connectors and mounting features arranged for use in compact multi-axis systems.
