HDS03.1-W100N-HA13-01-FW
The HDS03.1-W100N-HA13-01-FW is a drive controller produced by Bosch Rexroth Indramat as part of the HDS Drive Controllers series. Within an automated cell, the unit receives velocity or torque commands from the higher-level control system. It processes feedback and energizes servo motors so that coordinated movement can be maintained across gantries, presses, or machining centers. This control role supports synchronized axis motion where repeatable response is required during acceleration, deceleration, and steady-state operation.
This controller communicates with the master control system through an analog command interface, allowing continuous reference signals for precise speed regulation. This interface supports continuously variable reference values rather than step-based network commands. During operation, it can deliver up to 100 A of output current to connected motors, supporting high-torque applications without additional amplifiers. Thermal stability is managed by a built-in air blower that directs cabinet air across the heat sink and removes heat without external ductwork. The airflow path helps cool the power section during sustained load. The unit belongs to the DIAX04 controller family and follows the signal and mounting conventions of that platform. The product is part of Line 03, which indicates the mechanical layout and board allocation.
The unit is Version 1. Functionally, it remains an HDS Drive Controller that closes the current loop for digital or analog servo axes while using the same backplane bus for a shared DC link. Current regulation is handled inside the module, while the shared bus structure supports integration with the rest of the drive system. The housing contains the blower, current stage, and logic interface in one module. This layout helps reduce panel depth and shortens wiring runs between the supply unit, encoder connectors, and motor leads.
