Product Description:

The HDS04.2-W200N-HA25-01-FW is a modular axis drive released by Bosch Rexroth Indramat within the HDS Drive Controllers series. Designed to regulate three-phase servo or spindle power modules in the DIAX04 platform, it converts motion commands from higher-level control systems into coordinated motor currents. In automated machining cells, transfer lines, and material-handling gantries, the unit functions as the central command element for an axis. It closes the current loop, supports precise torque and velocity control, and monitors thermal and electrical limits during operation. That role allows the connected motor to respond accurately to changing load conditions and command updates from the machine control.

It accepts reference signals through an ANALOG command interface, so speed or torque setpoints reach the controller as voltage levels processed in real time. The unit is part of the DIAX04 family, so it uses the same backplane connector system as related power modules and feedback cards. The drive can deliver up to 200 A of continuous output current, which is the maximum current it can sustain without derating. Heat is removed by a built-in air blower that directs airflow across the heat sink during high-load operation. The unit is Version 2, indicating the second version of this controller type.

The unit is classified as an HDS Drive Controller and is part of Line 04. In a coordinated multi-axis rack, it exchanges real-time current commands over the shared backplane. This arrangement supports coordinated operation with compatible motors, encoders, and inverters in the same rack. Because the controller is used in rack-based assemblies, the physical format supports organized module placement and direct connection to adjoining drive components. Signal exchange remains internal to the rack, which keeps intermodule wiring short.
