HDS03.2-W100N-HA03-01-FW
The HDS03.2-W100N-HA03-01-FW is a drive controller manufactured by Bosch Rexroth Indramat for the HDS Drive Controllers series. Within an automation cabinet, it produces regulated three-phase output for servo axes by converting energy from a shared DC bus into controlled motor current. This arrangement supports centralized axis control in machines that require rapid positioning, spindle acceleration, or coordinated motion across several axes. It works as the power stage between the supply modules and the connected motors, so the motion system can respond accurately to command signals from the higher-level controller. The controller is used where multiple drive components are grouped in one cabinet and the axis power must be handled in a compact, rack-based layout.
The controller is part of the DIAX04 platform and is assigned to Line 03. Command values enter through an analog interface, where voltage or current references are processed by the control electronics and applied to the output stage. During operation, the unit can supply a continuous motor current of 100 A, which suits medium-frame rotary or linear servomotors that need strong acceleration capability under sustained load. Heat is removed by a built-in internal air blower, so the power section remains cooled without external ducting. This cooling method supports dense cabinet layouts where several modules operate side by side and consistent airflow through the drive is needed.
The unit is Version 2. This release incorporates refined gate drivers and updated diagnostics while preserving the controller’s role in a shared-bus drive system. Protective functions work with external supply and ballast modules in the rack, so returned energy and fault handling can be managed at the system level. Status monitoring remains integrated in the drive electronics, allowing the control system to track axis behavior through the same module that performs power conversion. It is suited to centralized motion cabinets where several servo axes draw from one power structure while remaining individually regulated.
