HDS03.1-W100N-HS57-01-FW
The HDS03.1-W100N-HS57-01-FW is a modular drive controller manufactured by Bosch Rexroth Indramat and supplied within the HDS Drive Controllers series. It serves as the central command element for servo and spindle axes, converting high-level motion profiles into regulated current, velocity, and position loops. In automated machining cells, packaging lines, and material-handling systems, the unit links the programmable logic controller with individual motors and coordinates closed-loop motion control for connected axes. This allows commanded speed changes, torque requests, and position corrections to be processed in one control stage rather than split across separate motion modules. It also coordinates protective responses between the control section and the attached power components during normal machine operation.
The controller exchanges real-time motion data over the optical SERCOS interface, allowing synchronized axis updates with minimal jitter. It provides a continuous output current of 100 A, which suits applications that require sustained motor current during normal operation. Thermal management is handled by a built-in air blower, so the unit uses filtered cabinet air for cooling instead of relying on external cooling hardware. The identification code includes 03 for the line and 1 for the version. The unit is an HDS Drive Controller that installs beside compatible power inverters and feedback modules without additional interface boards.
Within the DIAX04 controller family, this model functions as the closed-loop coordinator that links multiple axis modules in a shared fiber-optic ring. As part of the HDS Drive Controllers series, it is intended for multi-axis installations where communication timing must remain consistent from one module to the next. Fiber cabling simplifies wiring because timing and status data for downstream devices travel on the same loop, which reduces separate communication runs inside the cabinet. That layout also helps keep signal routing organized when several drive modules are installed side by side. The result is orderly communication between axes without separate point-to-point control links for each module.
