HDS03.2-W075N-HA11-01-FW
The HDS03.2-W075N-HA11-01-FW is a drive controller built by Bosch Rexroth Indramat for the HDS Drive Controllers series. Within an automation rack, it processes command signals and supports regulated power delivery so connected servo axes can follow programmed motion accurately. The unit serves as the link between higher-level control commands and the motor power stage, allowing coordinated positioning and speed control in multi-axis equipment. It monitors command execution and fault limits in real time, helping the controlled axis respond predictably during acceleration, steady motion, and deceleration. Its rack-based format suits installations where several motion modules operate together in one enclosure.
Command signals reach the unit through an analog interface, allowing velocity or torque references to be transmitted as ±10 V signals from compatible control platforms. The controller belongs to the DIAX04 family, so its backplane connections and diagnostic behavior match other modules used on the same platform. Thermal management is handled by a built-in internal air blower, which moves cabinet air across the heat sink and removes heat without external ducting. The integrated fan keeps air moving over the heat sink when the controller is installed alongside neighboring modules in a compact rack. The power stage is rated for a continuous output of 75 A, allowing sustained motor current during normal operation before protective limiting occurs. This arrangement supports analog command systems that need direct reference handling and stable thermal control.
The unit is part of Line 03 in the product range. Its electronics correspond to Version 2, indicating the second revision of this design. In a cabinet, the module uses common spacing and shared bus connections that support side-by-side mounting with companion units. Shared bus connections reduce the need for separate jumper arrangements between adjacent modules. Front access remains available for status viewing and signal connections during operation.
