Product Description:

The HDS03.2-W075N-HA04-01-FW is a drive controller manufactured by Bosch Rexroth Indramat in the HDS Drive Controllers series. It serves as the power and command interface between a motion control CPU and connected servo motors, translating incoming reference values into controlled motor operation for coordinated axes, feed drives, and spindle tasks. The unit converts those commands into regulated three-phase output, allowing the motor to receive the voltage and current needed for accurate motion in industrial automation equipment. This arrangement lets the controller respond to changing setpoints while maintaining stable motor operation during acceleration, deceleration, and load variation.

This controller can deliver a continuous output of 75 A, which suits medium-power servo applications without the need for an external current booster. Motion commands reach the device through an analog interface, so ±10 V velocity or torque references from a CNC or PLC can be processed directly. Thermal management is provided by a built-in air blower that pulls cabinet air through the heat sink to keep the power section within its normal operating range. The blower uses internal cabinet airflow, so no separate ducted external cooling path is required. As part of the DIAX04 family, the unit uses the same backplane style and DC bus connections found in related multi-axis systems, which helps it fit into established rack layouts.

The controller is part of Line 03 and is released as Version 2. These identifiers distinguish the product generation within this platform without changing its basic role as the power stage between the control system and the motor. The housing combines current regulation, velocity-loop processing, and protective monitoring in one module. It also follows the same mechanical and wiring layout used across the wider product platform, which supports consistent installation in matching multi-axis assemblies.
