HDS03.1-W075N-HA11-01-FW
The HDS03.1-W075N-HA11-01-FW is a modular drive controller manufactured by Bosch Rexroth Indramat for use within the HDS Drive Controllers series. In a DIAX04 cabinet, the unit works with a power supply and a motor feedback card to create a closed-loop axis. It converts reference commands from a motion CPU into controlled three-phase current for servo or spindle motors. This supports coordinated positioning, speed control, and torque regulation in packaging lines, machine tools, and material-handling stations. Because the controller regulates motor current directly, the higher-level control can command motion profiles with repeatable response during acceleration, constant speed, and deceleration.
At the motor terminals, the controller can deliver a continuous output of 75 A, so it can support high-inertia loads without thermal derating during steady operation. Command data reach the module through an analog interface, so velocity or torque setpoints are supplied as differential voltage signals rather than through a fieldbus. This arrangement is useful in systems that use external analog command sources and need direct response from the drive stage. During operation, heat is removed by a built-in air blower, which pulls air through the heat sink for cabinet installation. The unit is listed as Line 03 and belongs to the DIAX04 family, so its mechanical format and diagnostics follow that platform.
It can pair with HMS or HVE power supplies without adapters, which supports integration in the same rack system. The product category is HDS Drive Controller, a designation used for this control and power stage. The design is released as Version 1, and the electrical footprint remains constant across production batches. The module format is intended for rack-based installation, where separate supply and feedback components are arranged around the controller instead of being built into a single housing.
