HDS03.1-W075N-HA26-01-FW
The HDS03.1-W075N-HA26-01-FW is a drive controller produced by Bosch Rexroth Indramat within the HDS Drive Controllers series. Housed in a card-style enclosure for backplane installation, the unit accepts low-level reference commands from CNCs or PLCs and modulates the power bus to actuate connected servo amplifiers. In industrial automation, it coordinates velocity, position, and torque across multiple axes so machine tools, pick-and-place robots, and conveyor sections can maintain repeatable motion under changing mechanical loads. This operating role lets the controller respond to external motion commands while the larger drive system manages power distribution and feedback processing.
It accepts setpoints through an ANALOG command interface, so ±10 V speed or torque references can be wired directly from legacy process controllers. This keeps the unit compatible with control schemes that still use analog command wiring rather than fieldbus-based references. The output bridge is rated for 75 A, enabling the module to drive large servomotors without exceeding its continuous current capacity. Excess heat is removed by a built-in air blower, which helps keep semiconductor temperatures within an acceptable operating range when cabinet airflow is limited. As part of the DIAX04 platform, the controller fits shared power supply and interface modules used in that system.
The product is assigned to Line 03 and uses Version 1 electronics. These identifiers place the unit within a specific design release of the platform. The controller uses the same backplane mounting approach as companion modules, which supports orderly cabinet layout in multi-axis racks. Its function remains centered on regulated axis control, with command signals entering from the higher-level control system and power conversion taking place inside the coordinated drive assembly.
