HDS03.1-W075N-HA29-01-FW
The HDS03.1-W075N-HA29-01-FW is a drive controller produced by Bosch Rexroth Indramat for the HDS Drive Controllers series. It converts DC bus energy from a supply module into controlled three-phase output for servo motors used in machining, printing, and material-handling equipment. Acting as the axis amplifier in a distributed motion system, it receives velocity or position references from a master control platform and modulates current accordingly. This lets the connected motor respond with controlled acceleration, deceleration, and holding behavior during repetitive automated motion. The result is stable axis control for machines that require coordinated movement across multiple operating cycles.
The controller has a continuous output capability of 75 A, which is the maximum RMS phase current the power stage can deliver under steady thermal conditions. Heat is removed by a built-in air blower, so forced internal airflow helps maintain heat sink temperature without the need for external ducting. Motion commands enter through an analog interface, which allows direct reference signals to be interpreted by the control card for real-time regulation of speed or torque. The unit is part of the DIAX04 family, placing it within the same controller platform used for coordinated multi-axis systems. This arrangement suits applications where one control system manages several servo axes at the same time.
The product is part of Line 03 in the series, which corresponds to its mechanical frame size and connector layout. The controller is Version 1, indicating the first standard release for this frame. These identifiers distinguish the unit within the product hierarchy and separate it from other controller lines in the range. They also keep the model classification clear when the drive is used with other modules in the same system. That makes the unit’s placement easier to follow during installation and system integration.
