HDS04.2-W200N-HA21-01-FW
The HDS04.2-W200N-HA21-01-FW drive controller is manufactured by Bosch Rexroth Indramat and belongs to the HDS Drive Controllers series. Installed in an industrial automation rack, it supplies regulated DC-link energy to servo inverter modules, closing the power loop between the main supply unit and individual motor axes. This arrangement lets the controller regulate energy flow between the rack supply and the connected axis amplifiers during acceleration, steady operation, and deceleration. By converting command references into controlled current and voltage, it lets connected motors follow dynamic position and velocity commands generated by a higher-level motion processor. Used in machining centers, packaging equipment, and material-handling cells, the unit supports rapid acceleration profiles while protecting upstream fuses and bus capacitors.
Accessory modules can be attached to its front connector, and the device is grouped under the DIAX04 modular family so identical units can share a common DC bus. Incoming command values reach the controller through an analog interface, so standard ±10 V velocity or torque references from PLC motion cards can be wired directly without fieldbus converters. This approach supports control systems that use voltage-based motion commands instead of serialized network communication. The internal power path is rated for 200 A of continuous current, which is the maximum load the shared bus can support before protective limiting occurs. Temperature rise is managed by a built-in air blower that draws cabinet air across the heat sink and supports cooling in densely packed enclosures.
The hardware belongs to line 04, and the control logic uses second-generation signal processing for faster current loops. The unit is version 2, so its parameter sets should match that revision. It fits beside supply modules of the same width, which helps keep bus-bar alignment consistent across the rack. Side-by-side installation also preserves the modular layout used in multi-axis cabinets.
