HDS03.1-W100N-HS55-01-FW

The HDS03.1-W100N-HS55-01-FW is a drive controller manufactured by Bosch Rexroth Indramat and assigned to the HDS Drive Controllers series. Inside a motion system, it accepts digital commands, regulates motor current, and contributes to precise axis positioning. By executing these functions, the unit provides the electrical link between a higher-level control platform and servo actuators in industrial automation.

On the communication side, the controller uses the SERCOS fiber-optic interface, allowing deterministic command and feedback exchange with a master drive or PLC. Its power stage is rated for 100 A, enabling sustained high-torque operation for demanding servo axes. Heat produced during these duty cycles is removed by a Built-in Internal Air Blower, so cabinet airflow is managed without external cooling assemblies. The unit belongs to the DIAX04 controller family; this membership aligns connector placement, configuration tools, and firmware structure with other devices in the same bus stack. Functionally it is classified as an HDS Drive Controller, indicating that its firmware executes current-controlled servo loops and supports rapid parameter download when the SERCOS ring is initialized.

Hardware identifiers carried in the type code supply additional detail. The line designation is 03, which marks the mechanical layout used for mounting rails and auxiliary bus bars in this release. Firmware carrier revision Version 1 is installed, so parameter compatibility should follow that specific revision tree.  Because it remains part of the HDS Drive Controllers range, the module slides into the common DIAX04 power rack without requiring unique spacers or wiring accessories.
