HDS03.1-W075N-HT04-01-FW
The HDS03.1-W075N-HT04-01-FW is a drive controller from Bosch Rexroth Indramat in the HDS Drive Controllers series. It occupies a power slot within multi-axis cabinets and converts DC-bus energy into phase-controlled output for servo motors, allowing multiple motion modules to share a common supply and regenerative line inside compact drive assemblies. By linking motor power stages to higher-level logic, the unit supports accurate torque and speed control in machine tools, printing lines, and automated assembly stations. This arrangement allows several coordinated axes to run from a common electrical platform while remaining under centralized motion supervision.
This controller exchanges deterministic telegrams over the fiber-optic SERCOS ring, allowing synchronized setpoint delivery and status feedback across axes that must follow timed motion profiles. Its continuous output capability is 75 A, which is its rated current under steady thermal conditions rather than a short-duration overload figure. The unit belongs to the modular DIAX04 family, so its mechanical outline and backplane connectors match companion amplifiers used in the same cabinet architecture. Thermal energy generated by IGBT switching is removed by a built-in air blower, which moves cabinet air across the heat sink without external ductwork and supports stable operation during sustained current demand.
The unit is part of Line 03 and is released as Version 1. Its optical command interface carries control data between the controller and the higher-level motion system, supporting coordinated responses to changing position and speed commands. The rack-mounted format supports installation beside related drive modules in shared cabinets, which helps keep grouped axis layouts organized. Because the controller is intended for modular drive systems, it can operate as one element in a larger motion package rather than as a standalone power stage.
