Product Description:
The HDS03.2-W075N-HA08-01-FW is a drive controller produced by Bosch Rexroth Indramat. As a modular servo drive unit, it supplies regulated power to compatible synchronous and induction motors while exchanging command references with higher-level PLCs. In automated machinery, the device coordinates velocity, torque, and position loops so that axes follow programmed motion profiles without drift. This allows a connected motor to respond smoothly during indexing, feed motion, and other repeatable machine movements. Because the controller manages both the power stage and loop response, it suits machine axes that require stable speed changes and consistent positioning.
Command data reach the controller through an analog interface, so the axis card interprets differential voltage levels instead of serial fieldbus signals. During operation, the power section can deliver a continuous 75 A of output current, which indicates the current capacity available for sustained motor demand. Thermal energy from the switching devices is removed by a built-in internal air blower, so airflow moves across the heat-sink fins without external ducting. The control section is part of the DIAX04 family, allowing the unit to operate within that platform’s shared DC bus and backplane arrangement. The product is part of Line 03 in the series.
The drive is Version 2. It is classified as an HDS Drive Controller, which distinguishes it from dedicated supply modules in the same platform. The unit belongs to the HDS Drive Controllers series and serves as the axis power stage in a modular multi-axis system. Its role is to convert incoming control references into regulated motor current for one axis while remaining electrically coordinated with the rest of the drive assembly. This arrangement supports coordinated motion where several drives operate on a common platform while each axis maintains its own closed-loop control.
