Product Description:

The HDS05.2-W300N-HA30-01-FW is a drive controller from Bosch Rexroth Indramat in the HDS Drive Controllers series. Installed in multi-axis cabinets, it closes current and velocity loops so servo or spindle motors can follow motion commands from a CNC or PLC. It acts as the power stage between the DC bus and the connected motor, converting control input into regulated motor current for demanding industrial axes. That function lets the connected axis respond to changing load conditions while maintaining commanded speed or torque. In automated cells, the module also performs protective shutdowns if overload, short-circuit, or command-loss conditions occur.

The controller can source up to 300 A of motor current, allowing it to operate high-torque axes such as extruder screws, main spindles, or heavy positioning tables. Command signals enter through an analog interface, and the reference is carried as ±10 V levels that suit many legacy motion cards. Because the command input is analog, the controller can be integrated with control systems that output conventional voltage references instead of digital network commands. Internal components are cooled by a built-in air blower, which moves cabinet air across the heat sink without external ducting. This airflow helps remove heat from the power section during sustained load and repeated acceleration cycles.

The unit is part of the DIAX04 platform, so it works with supply modules and inter-bus communication boards used in that system. Within the product range, it belongs to Line 05, which groups units with the same general power class and mounting format. That arrangement supports a consistent module layout in cabinets that combine power supply, communication, and axis control sections. The drive is Version 2, indicating the product revision used for this controller. The line and version codes identify where this unit fits within the series and distinguish it from earlier revisions.
