HDS04.2-W200N-HA34-01-FW
The HDS04.2-W200N-HA34-01-FW module is a drive controller produced by Bosch Rexroth Indramat for the HDS Drive Controllers series. Within a multi-axis rack, the unit closes the power loop between a supply module and the servo motors it controls, converting reference commands into regulated three-phase output. Its purpose in industrial automation is to deliver controlled torque and speed so that machining centers, printing lines, and assembly cells can synchronize motion without mechanical drift. This role lets the controller support accurate axis response during coordinated motion tasks that depend on stable current regulation.
In operation, the controller accepts reference values over the analog command interface, so ±10 V signals from a CNC or PLC are converted directly into drive current without a digital fieldbus layer. Its power stage is rated for a continuous current of 200 A, allowing connected servo axes to accelerate heavy loads without saturating the drive electronics during sustained demand. Thermal management is handled by a built-in air blower that circulates cabinet air through the heat sink, helping remove heat generated by the output stage. Because cooling is integrated into the unit, external ducting is not required and cabinet layout can remain more compact around the drive section. That arrangement allows the controller to respond directly to continuously varying command levels used by CNC and PLC systems with analog motion interfaces.
The unit belongs to the DIAX04 controller family, and the designation Line 04 places it within that product line. The drive is Version 2, indicating the second release for this model. In a DIAX04 rack, that grouping means the controller follows the same general mechanical size and connector arrangement used by related modules. It is intended to work in systems that use analog command control and a shared supply structure for multiple axes.
