HDS03.1-W075N-H
The HDS03.1-W075N-H is a drive controller produced by Bosch Rexroth Indramat within the HDS Drive Controllers series. In automated production cells, the unit links to power-supply modules and feedback loops to apply vector-based current regulation, letting multiple servo axes follow synchronized speed or position profiles. Acting between the motion planner and the motor windings, it converts digital setpoints into precisely modulated pulses so that packaging machines, transfer lines, and CNC stations maintain repeatable cycle times. The controller receives commands from the higher-level motion system and applies them at the motor level in real time. It serves as the motor-side control stage in a rack-based multi-axis system.
Its electronics are mapped to the DIAX04 controller family, meaning it occupies a standardized rack slot that shares a common DC bus and SERCOS fiber-optic diagnostics with adjacent axes. The power bridge is rated for 75 A of continuous output, allowing sustained current delivery for demanding servo applications. To keep junction temperatures within safe limits, a built-in air blower moves airflow across the heat sink, eliminating the need for external ductwork. The unit is part of Line 03 in the series. This rack-based format helps integrate several axes in one compact cabinet without separate standalone housings.
The unit is Version 1. Its classification as an HDS Drive Controller distinguishes it from separate HVE supply modules that feed the DC link. This arrangement lets the controller focus on motor current and motion response while the supply module handles bus energy for the rack. It therefore fits systems in which supply, control, and axis modules are separated into dedicated rack components. The shared platform also supports orderly expansion of multi-axis systems that use the same bus structure.
