Product Description:

The HDS04.1-W200N-HA02-01-FW is a drive controller module manufactured by Bosch Rexroth Indramat and assigned to the HDS Drive Controllers series. It occupies the supply position in a DIAX04 rack and provides the regulated intermediate-circuit energy that individual servo inverters require for closed-loop motion control. In CNC machine tools and automated handling stations, the unit manages braking energy recovery, distributes DC bus power to multiple axes, and supervises protective shutdowns during overcurrent or overvoltage conditions. This arrangement allows several connected axes to operate from one central supply stage rather than from separate power modules.

This controller can deliver a continuous output of 200 A, so cabinet wiring, fusing, and busbars must be sized for that steady current level. Axis setpoints enter through an analog command interface, so velocity or torque references are transmitted as differential voltage signals rather than through a fieldbus connection. Thermal loads are removed by a built-in air blower, which moves air across the heat sinks and eliminates the need for external ducting. The unit is part of the DIAX04 family, so it matches the rack format and electrical arrangement used by related modules. The product is Version 1, indicating the first released design revision.

Inside an HDS Drive Controller rack, the module occupies the designated power section rather than an individual axis slot. Its line designation of 04 matches the mechanical format used for this size, so it aligns with neighboring devices in the same cabinet tier. From that position it feeds the shared DC bus, allowing connected servo inverters to draw intermediate-circuit energy during motion and return braking energy during deceleration. This layout supports multi-axis systems in which one supply module serves several inverters within the same rack. It also centralizes protective functions for the group of connected axes.
