HDS03.2-W075N-HA21-01-FW
The HDS03.2-W075N-HA21-01-FW drive controller is supplied by Bosch Rexroth Indramat within the HDS Drive Controllers series. Designed for multi-axis automation, the unit converts DC bus energy from a central supply into precisely regulated armature currents so servo motors follow commanded velocity, position, or torque profiles. By linking motion commands to power semiconductors and feedback loops, the controller serves in DIAX modular drive stacks used in packaging lines, machine tools, and material-handling systems. This arrangement supports velocity regulation, point-to-point motion, and synchronized axis control where the power stage must respond quickly to changing load conditions.
The controller is part of the DIAX04 family, so parameter sets, I/O blocks, and diagnostics match companion drives in the rack. Command references reach the device through an analog interface, allowing ±10 V speed or torque signals from legacy PLCs without protocol conversion. A continuous output capacity of 75 A supports medium-frame motors while maintaining stable current control. Thermal management relies on a built-in air blower, so cabinet airflow should support front-to-rear passage through the unit. The product is part of Line 03, which keeps mounting and connector placement consistent with matching HDS carriers.
The drive controller is Version 2, with updated fault handling, higher current-loop performance, and broader parameter coverage. The module can be used with supply units and communication cards to build axes of up to 11 kW each. In a modular rack, this layout separates power conversion, command handling, and machine-level communication into coordinated sections. It also allows the controller to fit into existing multi-axis assemblies that rely on the same rack structure and shared DC bus arrangement.
