Product Description:

The HDS03.2-W075N-HT29-01-FW is a drive controller produced by Bosch Rexroth Indramat. It belongs to the HDS Drive Controllers series and operates as part of the DIAX04 motion platform. In service, it interfaces between a CNC or PLC and a servomotor, regulating current and velocity loops for coordinated axis movement. It is used in multi-axis motion systems that require closed-loop control of speed and current during positioning tasks. This role supports precise response and synchronized operation in industrial automation cells.

Communication relies on the SERCOS fiber-optic interface, which provides time-synchronized telegrams for position, velocity, and diagnostic data. Within the DIAX04 controller family, the unit is in Line 03, which identifies the mechanical dimensions, mains connector style, and allowable bus extenders used by this controller type. Hardware version 2 adds improved gate-drive circuitry while keeping the established field wiring arrangement unchanged. The fiber-optic data exchange also helps keep command timing aligned across connected axes in coordinated motion systems. These characteristics support integration with compatible supply modules and related platform components.

The integrated power stage delivers a continuous output of 75 A, so incoming supply conductors, fuses, and contactors must be sized to carry that load under peak ambient temperatures. Heat generated by the switching devices is removed by a built-in internal air blower mounted behind the heatsink, where it draws cabinet air across the cooling fins. This airflow path supports rated load operation without external ductwork and helps maintain stable thermal behavior during sustained servo duty. The controller is intended for cabinet installation where its cooling air path and power connections can be accommodated by the surrounding system layout. This arrangement keeps the thermal path straightforward while supporting continuous operation within the drive system.
