HDS03.1-W075N-HA34-01-FW
The HDS03.1-W075N-HA34-01-FW is a drive controller manufactured by Bosch Rexroth Indramat for the HDS Drive Controllers series. It serves as the power stage and control interface in DIAX servo systems, allowing coordinated speed and torque regulation for motors used in packaging lines, printing presses, and material-handling gantries. By converting incoming control signals into regulated motor current, the unit supports precise axis response during continuous production cycles. This arrangement lets one module handle current delivery and control functions for machinery that depends on stable motion across repeated operating cycles.
The unit exchanges velocity and torque references through an analog command channel, so the upstream motion card supplies continuously variable voltage signals that the controller can read in real time. Its output stage supplies up to 75 A of continuous motor current, setting the available current level for sustained axis operation. Thermal energy at this load is removed by a built-in air blower, which eliminates the need for external ducting and helps maintain compact cabinet layouts. The controller is part of the DIAX04 family and is in Line 03, so it uses the common backplane and monitoring bus associated with that platform while indicating the specific design line of the unit.
The controller is Version 1, so it uses the baseline command set for this revision. Within a cabinet, the module is an HDS Drive Controller and occupies a double-wide slot in the drive rack. It accepts shared DC bus power from adjacent supply modules, which supports use in multi-axis assemblies where several drive components operate from the same power structure. The housing format suits modular installation beside companion units that handle supply, feedback, and coordinated axis control.
