HDS03.2-W100N-HA21-01-FW
The HDS03.2-W100N-HA21-01-FW is a drive controller manufactured by Bosch Rexroth Indramat for the HDS Drive Controllers series. Within multi-axis drive racks, it provides the power stage and regulation needed to operate servo motors in industrial automation cells. By converting command voltages into controlled motor currents, the unit acts as the closed-loop interface between a motion control host and the mechanical axis. This arrangement supports positioning, speed control, and torque regulation in machine tools, packaging equipment, and transfer systems where stable axis response is required.
This controller uses an ANALOG command interface, so the master device sends continuous voltage references instead of digital fieldbus telegrams. Thermal management is handled by a built-in air blower, which moves cabinet air across the heat sink without external ducting. The power electronics support a continuous output of 100 A, allowing the module to supply medium-frame Indramat motors in typical duty cycles. Control behavior corresponds to the DIAX04 platform, so the unit fits established rack layouts and operating methods used in that system. Analog command operation is useful where the higher-level controller provides direct velocity or torque reference signals through conventional control wiring.
The unit is classified as an HDS Drive Controller. It is Version 2 and belongs to Line 03 of the product range. Common mounting dimensions and bus connections let it fit standard rack layouts used with this controller family. The HA21 designation identifies the analog command configuration used by this model, while the front-mounted module format supports installation in cabinet-based drive assemblies. Its role in the rack is to provide regulated motor current for a commanded axis while operating with the associated supply and control hardware.
