HDS03.1-W075N-HS30-01-FW
The HDS03.1-W075N-HS30-01-FW is a digital servo drive controller manufactured by Bosch Rexroth Indramat and assigned to the HDS Drive Controllers series. Installed in a modular drive rack, the unit works with power converter modules and feedback loops to regulate servo motors in automated assembly cells, packaging lines, and material-handling axes. By translating high-level motion commands into phase-accurate current, the controller maintains commanded speed, torque, and position, enabling coordinated multi-axis movement throughout an industrial automation platform. This type of controller is typically used where several axes must accelerate, decelerate, and hold position in sync under a central motion system.
Its communication port supports the SERCOS fiber-optic interface, so positioning and diagnostic data are exchanged over a deterministic real-time bus rather than through discrete wiring. The controller belongs to the DIAX04 family, so it shares a common backplane and parameter structure with other axis modules in that platform. A continuous output capacity of 75 A is the maximum motor phase current the unit can modulate without derating, which directly affects the torque available from connected servomotors. Thermal stability is maintained by a built-in air blower, which circulates cabinet air through the heat sink and eliminates the need for external ducting. The unit is part of Line 03, which matches the mechanical dimensions and terminal layout used for this HDS design line.
The controller is Version 1. It uses a standardized mounting pattern and diagnostic LED layout, which keeps rack installation straightforward and consistent with related modules. The front-panel indicators remain visible when modules are mounted side by side, so operating states can be checked directly at the rack. The unit remains part of the HDS Drive Controllers series, and it follows the same panel wiring paths and cooling airflow arrangement used across that series.
