Product Description:

The HDS05.2-W300N-HA05-01-FW is a drive controller produced by Bosch Rexroth Indramat and assigned to the HDS Drive Controllers series. Within an automation cell, it links a DIAX axis module to the supply unit and servo motor, allowing velocity and torque control over a shared DC bus. This role makes the unit suitable for modular motion systems in machine tools, printing lines, and material-handling gantries. It works in applications where the controller and power section must respond quickly to load changes while remaining coordinated with the rest of a cabinet-based axis group. Its cabinet-mounted format supports multi-axis layouts in which the supply section and motor connections are handled as separate modules.

The controller exchanges setpoint and feedback signals over an analog command interface, so host PLCs provide continuous reference voltages instead of digital telegrams. Current delivered to the motor windings can reach a sustained 300 A, which supports large-frame servomotors without derating under continuous demand. Internal heat is removed by a built-in air blower, so mounting requires unobstructed inlet and exhaust openings and does not depend on an external heat sink or liquid circuit. Compatibility with the DIAX04 controller family keeps card dimensions and parameter handling consistent with other axes in the same cabinet. This arrangement suits systems that use analog control architecture and shared cabinet space for multiple coordinated drive modules.

The unit is Version 2, which indicates the second hardware release used for this model. It is part of Line 05, and the wide-bandwidth current regulator in this line supports fast response to torque commands during dynamic speed changes. The module uses the same backplane pinouts as other units in the range, which helps it fit existing Rexroth racks without changing the basic cabinet layout. That consistency is useful in systems where several axes are installed side by side and rely on matching electrical interfaces.
