Product Description:

The HDS05.2-W300N-HA20-01-FW is a modular drive controller from Bosch Rexroth Indramat in the HDS Drive Controllers series. The unit interfaces between the power supply section and the servo or spindle motor it controls. By processing velocity and torque setpoints from an external motion card, it converts those commands into regulated three-phase output for closed-loop axis control in production cells, machining centers, and automated transfer lines. This operating role lets the controller respond to changing load demands while maintaining accurate motion across a wide range of industrial axis applications.

Control data reach the module through an analog command interface, so the drive accepts differential ±10 V reference signals from PLCs or motion boards with minimal conversion delay. The power stage is rated for 300 A, which is the continuous output current available for a single high-inertia axis under normal thermal conditions. Compatibility with the DIAX04 controller family means the encoder feedback bus and diagnostic protocol align with other axes in the same rack, which helps maintain consistent communication behavior in multi-axis systems. A built-in air blower moves cooling air across the IGBT heat sink, allowing cabinet installation without external ducting while helping keep semiconductor temperatures within limits when the drive operates at full current.

The base hardware code 05 sets the mechanical dimensions and connector placement for this controller size. Because the connectors follow that hardware code, cabinet wiring can stay consistent across matching controller sizes. It is identified as an HDS Drive Controller, so parameter files and service software can recognize the module when it is installed in the rack. The unit is Version 2, indicating the second hardware revision for this model.
