HDS03.1-W100N-HS03-02-FW
The HDS03.1-W100N-HS03-02-FW is a modular axis drive controller from Bosch Rexroth Indramat in the HDS Drive Controllers series. It is designed for installation in a multi-axis automation rack, where it converts motion commands from a higher-level control system into regulated current references for connected servo power sections. By controlling position, speed, and torque loops, the unit supports accurate motion in CNC machines, packaging lines, and material-handling equipment. Its rack-mounted format helps keep the control section compact in cabinets that group several coordinated axes together. This arrangement also allows the drive system to be organized in a clear modular layout.
Communication with the motion supervisor takes place over the SERCOS optical bus, which provides deterministic transfer of command and feedback data. The controller can supply up to 100 A of continuous output current, making it suitable for axes that require sustained torque and strong acceleration response. Cooling is managed by a built-in air blower, so heat can be removed without routing cabinet airflow directly across the heat sink. The electronics are matched to the DIAX04 platform, which uses a common connector layout and control structure across related axis modules. This combination supports stable closed-loop operation when several drives must run in synchronization.
The product is part of Line 03 in the series. It includes error LEDs that provide direct visual status indication at the front of the unit during operation and fault conditions. The controller also supports parameter cloning, which allows the same operating data to be copied where identical axis behavior is required. Protective diagnostics are built into the drive, helping the control system respond to abnormal operating states before they affect commanded motion. These functions support consistent operation in automated equipment that depends on repeatable axis control.
