HDS03.2-W075N-HS73-01-FW
The HDS03.2-W075N-HS73-01-FW is a modular axis drive controller produced by Bosch Rexroth Indramat for the HDS Drive Controllers series. Integrated into multi-axis DIAX04 drive racks, it coordinates servo power modules with higher-level motion logic to actuate industrial machinery, conveyors, and process equipment. Within an automation cell, the unit serves as the command layer that links motion commands from the control system to the individual power stages, allowing precise speed, torque, and position regulation on electrically driven axes.
The controller relies on the SERCOS fiber-optic interface for command communication, and this deterministic network provides cyclic real-time data exchange so parameter changes and status updates occur within a fixed time slot on every control cycle. Cooling is handled by a built-in air blower that pulls cabinet air through the heat sink and helps maintain safe component temperatures without external fan trays. The power section is dimensioned for a continuous output of 75 A, which is the maximum RMS motor current the downstream drive modules may draw when the controller issues enable signals. The unit is part of the DIAX04 family, so it fits into backplanes that share a common DC bus and feedback cabling layout.
Within the HDS Drive Controllers hierarchy, the unit is part of Line 03, which matches enclosure depth and connector placement with companion supply and power modules in the same rack. The internal design is further specified as Version 2, indicating a second-generation control board with revised diagnostic LEDs and updated internal electronics. Classified as an HDS Drive Controller, the device carries only the logic, communication, and monitoring circuits, while the motor power stages remain separate and can be selected to match the load requirements of each axis.
