Product Description:

The HDS03.2-W075N-HT12-01-FW is a drive controller produced by Bosch Rexroth Indramat. Installed in cabinet-mounted automation racks, it converts network commands into regulated motor current so that conveyor sections, feeders, or positioners move according to program demands. By combining control electronics, power conversion, and diagnostic functions in one module, the unit reduces panel wiring and supports coordinated motion across multi-axis systems. Because it is intended for rack installation, it fits systems where several drive axes share a common control layout and centralized power distribution. Its control role is centered on delivering commanded torque and speed behavior while the surrounding machine controller manages the overall sequence of motion during continuous operation.

This controller exchanges setpoint and feedback data over the SERCOS fiber-optic interface, allowing deterministic communication with higher-level PLCs. A continuous output capability of 75 A indicates the maximum motor phase current the device can deliver without overheating. Thermal stability is supported by a built-in air blower that moves air across the heat sink and removes the need for external ducting. The unit is part of Line 03, and it belongs to the DIAX04 controller family, which uses common power-bus connections and mounting dimensions across related modules. The fiber-optic link also supports stable communication in electrically noisy industrial environments. This helps maintain predictable command updates during synchronized motion tasks.

The drive controller is Version 2, which places it in a later revision of the product line. It is part of the HDS Drive Controllers series and is classified as an HDS Drive Controller, confirming its use as a current-regulated axis module rather than a standalone power supply. In a modular drive system, this controller is used with separate supply hardware instead of serving as a mains input unit. That arrangement suits rack-based motion systems that divide incoming power conversion and axis regulation into different modules. The naming structure also keeps model identification clear when matching the unit with compatible system components.
