HDS03.1-W075N-HA24-01-FW
The HDS03.1-W075N-HA24-01-FW is a modular drive controller manufactured by Bosch Rexroth Indramat for the HDS Drive Controllers series. It is intended for multi-axis automation racks, where it works with matching supply and power modules to regulate servo motors, control acceleration and braking behavior, and support accurate axis response. By converting incoming setpoint commands into controlled motor current, the unit supports the closed-loop operation needed in material handling systems, machine tools, and packaging equipment. Its rack-based design also allows several coordinated axes to operate from the same cabinet structure without requiring a separate standalone controller for each motion task.
The unit uses an analog command interface, so velocity or torque references arrive as ±10 V signals for internal processing. The controller digitizes the incoming reference and applies it to internal regulation loops, which helps the axis react smoothly to changing commands. The power section provides a continuous output of 75 A, which allows the controller to operate medium-frame synchronous or induction motors under sustained load. Heat is removed by a built-in air blower, so cabinet layouts do not need external ducting around the controller itself. As part of the DIAX04 platform, the device shares back-plane bus geometry and common diagnostic behavior with compatible axes, which helps keep multi-axis system integration straightforward.
The controller is installed in the rack under Line 03, and compatible parameter sets recognize revision 1 for this unit. Its classification as an HDS Drive Controller indicates that the electronics for current, speed, and position regulation are contained in the module rather than placed on separate external cards. The unit pairs with separate supply modules in the same rack, which keeps the control section and the incoming power section functionally distinct. This layout supports orderly axis expansion in cabinet-based systems and keeps the controller focused on motor regulation, feedback processing, and coordinated motion response.
