Product Description:

The HDS03.2-W075N-HS70-01-FW is a modular drive controller produced by Bosch Rexroth Indramat within the HDS Drive Controllers series. It serves as the axis-specific power and control module in the DIAX04 automation platform, converting command data from the system bus into regulated motor currents. In multi-axis machining centers, pick-and-place gantries, and material-handling lines, the unit supplies controlled three-phase power while exchanging status information with higher-level motion controllers. This arrangement lets the controller translate network commands into motor output for demanding automation tasks that require repeatable acceleration and smooth speed regulation. Its role in the drive set allows one axis to respond quickly to commanded torque, speed, and position changes during coordinated machine motion.

Communication is carried out over the SERCOS fiber-optic interface, so velocity, torque, and diagnostic words are transferred with deterministic timing between the controller and the master. The unit is part of the DIAX04 family, and its plug-in format mates with other single-axis and supply modules on the common backplane. A continuous output capacity of 75 A allows it to drive medium-power servo motors without current derating across the rated speed range. Thermal energy is removed by a built-in air blower, which keeps the heat sinks at acceptable temperatures without external cabinet ducting. Deterministic transfer over the optical link helps the axis stay synchronized with other drives during interpolated motion and rapid cycle changes. The product is part of Line 03, which identifies this design line in the series.

The functional revision is Version 2, so the unit uses the parameter structure associated with this release. It is installed as an HDS drive controller in the modular drive set, and its connections follow the layout used for this controller type. The module works with supply units and motion cards that match its assigned revision, helping maintain proper communication and control behavior across the cabinet. The modular format also supports orderly cabinet placement, since the controller sits with related system components on the shared platform. Its slot-based arrangement keeps the axis module integrated with the rest of the drive system without adding external interface hardware.
