HDS03.2-W075N-HS24-01-FW
The industrial drive controller HDS03.2-W075N-HS24-01-FW is built by Bosch Rexroth Indramat and belongs to the HDS Drive Controllers series. Within a multi-axis cabinet, it regulates current, velocity, and position loops for servo motors, forming the power stage of a DIAX04 automation rack. By converting command data from higher-level motion processors into precisely timed power pulses, the unit coordinates synchronized motion on packaging lines, machine tools, and material-handling cells. Because the controller closes the drive loops inside the cabinet, it serves as the direct electrical link between the machine control and the connected motor axis.
The control loop receives its setpoints over the fiber-optic SERCOS interface, so deterministic telegrams from a master motion card reach the drive with minimal latency. Internally, it shares its platform with the DIAX04 controller family, allowing the same general cabinet arrangement and axis layout across related modules. Thermal management is handled by a built-in air blower, which pulls cabinet air across the heat sink and keeps semiconductor temperatures within limits without external ducting. The power section is rated for a continuous output of 75 A, which is the maximum RMS phase current available to a motor under steady load. Product coding places the device in Line 03.
The controller is Version 2, indicating the second release of the control electronics for this model. Mounting dimensions, connector styles, and diagnostic displays align with other drives in the platform, so the unit fits naturally into DIAX04 rack arrangements that use matching support modules. Its classification as an HDS Drive Controller indicates that it is intended for servo and spindle applications within that system. It is used where several coordinated axes share a common DC bus and a common control structure.
