Product Description:

The HDS03.2-W075N-HT19-01-FW is a modular drive controller manufactured by Bosch Rexroth Indramat for the HDS Drive Controllers series. Acting as an axis module within cabinet-mounted motion packs, the unit interfaces with surrounding servo drives and power supplies to issue current and velocity commands. Its role is to translate high-level motion instructions into regulated drive signals so that industrial robots, machining centers, and material-handling lines maintain the required position accuracy and cycle speed. Because it works as a modular controller rather than a standalone supply unit, it depends on the surrounding rack structure for coordinated multi-axis operation. This layout supports centralized cabinets in which several axes share system resources and synchronized control timing.

Inside a DIAX04 automation rack, the controller exchanges real-time data through the optical SERCOS network layer. This high-speed bus serves as the primary command interface, allowing synchronous setpoint transfer with tight cyclic times. Compatibility with the DIAX04 architecture keeps integration consistent with other modules in the platform. Power-stage capability is set by a continuous output rating of 75 A, giving the module enough headroom for medium-frame servo motors on heavy feed axes. Thermal stability is maintained by a built-in air blower, which draws cabinet air across the heatsink fins to prevent performance derating at elevated ambient temperatures. The optical link also helps reduce sensitivity to electrical noise in dense motion cabinets. The device is part of Line 03, so its connector layout and diagnostic LED positions match other 03-line modules in the platform.

The controller is Version 2. Within software menus, the unit identifies itself as an HDS Drive Controller, which groups functions appropriate for this product type. Motion control and diagnostic functions are handled internally, allowing the module to support closed-loop axis behavior without additional control hardware inside the drive slot. This identification also helps the connected system present the correct operating functions and status screens for the module. The base current rating and cooling method remain unchanged in this revision.
