HDS03.1-W075N-HS57-01-FW
The HDS03.1-W075N-HS57-01-FW is a modular drive controller built by Bosch Rexroth Indramat for the HDS Drive Controllers series. Positioned inside a DIAX04 servo cabinet, it links intelligent drive modules with central motion logic. The unit supervises motor current, velocity feedback, and position loops, converting bus telegrams into regulated power delivery for servo axes. In a closed-loop system, the controller reacts to command changes from the higher-level machine control and adjusts power delivery to keep axis motion stable during acceleration, deceleration, and synchronized moves. Used on packaging lines, transfer stations, and CNC machining centers, it supports precise multi-axis motion across interconnected automation cells during continuous production.
Command exchange is carried out over the SERCOS fiber-optic ring, giving deterministic cycle times and galvanic isolation from plant voltages. The unit is part of DIAX04, which identifies mechanical mounting points and power-bus compatibility for shared backplane installation with other drives. Thermal management is handled by a built-in air blower, so cabinet air moves through the heat sink without external ducts. The power stage is rated for 75 A, enabling the controller to energize large synchronous or induction motors at nominal mains voltage. Parameter blocks and diagnostics are exchanged through the same ring, so no auxiliary serial link is required.
The product is part of Line 03 and Version 1. It is classified as an HDS drive controller, and that designation matches the motor and feedback combinations supported by the platform. The module layout remains consistent with related units in the series, so it fits the shared cabinet structure used for multi-axis systems. Its format is suited to cabinets that combine several axes in one rack, where consistent spacing and interconnection support orderly system layout within automated equipment.
