Product Description:

The HDS03.2-W075N-HS96-01-FW is a modular axis amplifier manufactured by Bosch Rexroth Indramat for the HDS Drive Controllers series used in multi-axis racks. In an automation cell, this unit converts DC bus power into controlled three-phase output, allowing precise velocity and position regulation for a connected motor. Its role is to close the servo loop for packaging lines, machining centers, and material-handling stations where stable motion profiles are needed for repeatable operation. It is intended for closed-loop axis control, where the drive continuously compares commanded motion with motor feedback and corrects the output current as needed. This arrangement lets the drive respond quickly to command changes and load disturbances while maintaining smooth axis movement through the operating cycle.

This controller exchanges setpoints, actual values, and diagnostics through the fiber-optic SERCOS interface, providing deterministic timing between the drive and the PLC layer. The optical link supports synchronized command updates and fast status reporting during coordinated motion. It can deliver up to 75 A of continuous output current, which sets the available current for downstream axes under rated thermal conditions. Thermal energy created by the switching devices is removed by a built-in air blower, and the integral fan moves cabinet air across the heat sink without external ductwork. This cooling method depends on open cabinet airflow paths around the heat sink and fan inlet. Because it belongs to the DIAX04 family, its mechanical footprint and backplane connectors align with other modules in that platform.

The code 03 identifies the design line that matches specific power-supply and bus-module geometries. Revision 2 indicates the second hardware release. The unit is an HDS Drive Controller, which separates the power stage from supply, I/O, and safety modules in the rack layout. That separation allows system layouts in which power conversion, control, and auxiliary functions are installed as dedicated units. Within the cabinet stack, the amplifier is placed where the rack arrangement supports the connected motor axis and the shared DC bus structure.
