HDS03.2-W075N-HA12-01-FW
The HDS03.2-W075N-HA12-01-FW is a drive controller produced by Bosch Rexroth Indramat for the HDS Drive Controllers series. Within an automated cell, it operates as the power and regulation module that closes the current, velocity, and position loops between the motion system and connected servo motors. By converting reference values from the machine's PLC into precise torque commands, the controller supports coordinated multi-axis movement in machining, material handling, and assembly equipment. It regulates the electrical output sent to the motor so the commanded motion profile can be followed with stable speed and controlled acceleration. This operating role helps the axis maintain repeatable motion during start, run, and stop sequences.
This module belongs to the DIAX04 family and exchanges setpoint data through an analog command interface, allowing direct wiring to conventional motion cards or process controllers. That interface is useful in systems that send continuous command values rather than relying on a digital fieldbus. During operation, the internal power stage can supply up to 75 A of continuous output current, which indicates the motor current available without thermal derating under normal conditions. Heat generated by the switching devices is removed by an internal air blower, so cooling air is directed across the heat sink without requiring separate cabinet ductwork. This arrangement supports stable thermal behavior when the unit operates under sustained load in multi-axis applications.
The product is part of Line 03 in the series and is supplied as Version 2. It is classified as an HDS Drive Controller. Its mechanical footprint, mounting rails, and bus connectors match the rest of the platform, so it can be installed beside companion axis modules in the same cabinet without changing the basic module arrangement. This consistent format helps maintain orderly cable routing and shared bus connections in established multi-axis layouts. The unit is intended for use where standardized controller dimensions and coordinated axis control are important to the overall drive system.
