HDS03.1-W075N-HA28-01-FW
The HDS03.1-W075N-HA28-01-FW is a drive controller produced by Bosch Rexroth Indramat for the HDS Drive Controllers series. Within an automation system, the unit uses regulated DC bus power and switching functions so that servo axes in a multi-axis rack can follow motion commands with tight current control and coordinated speed loops. It is intended for industrial machine tools, printing lines, and handling stations where centralized control of several motors supports accurate positioning and repeatable speed regulation. This type of arrangement allows one rack to coordinate multiple motion channels while keeping the drive hardware grouped in a single cabinet area.
The controller handles motor groups that draw up to 75 A of continuous current, which sets the continuous output capability of the power stage. Command signals enter through an analog interface, which supports legacy CNCs or PLCs that send ±10 V velocity or torque references. This allows the unit to work with control systems that do not use digital network commands for axis setpoints. Internal components are cooled by a built-in air blower, which helps manage semiconductor temperature during prolonged operation without separate cabinet ducting. As part of the DIAX04 platform, the module uses a standardized backplane layout for installation in a central drive rack. The unit is Version 1.
The unit is part of Line 03 within the product range. It is classified as an HDS Drive Controller, a format used for high-current axis control modules in centralized drive systems. It belongs to the HDS Drive Controllers series and is used in rack-based drive architecture where power conversion and control functions are grouped in one module. This arrangement keeps related drive components in a common cabinet area and supports organized multi-axis installation.
