Product Description:

The HDS04.2-W200N-HA22-01-FW drive controller is produced by Bosch Rexroth Indramat and belongs to the HDS Drive Controllers series. This module functions as a central power stage for servo axes, converting DC bus energy into regulated three-phase outputs so DIAX04 automation systems can position machinery with controlled speed and torque. In rack-based motion systems, it serves as the regulated output stage between the shared DC bus and the connected servo motor. It links the motion control computer to the motor windings so that packaging lines, printing cylinders, and material-handling gantries receive precise motion commands. The unit also mates with a central supply module through the DC bus bars provided in the chassis.

The controller delivers a continuous output of 200 A, allowing it to energize multiple medium-inertia servomotors from a single rack slot. Motion commands enter through the analog interface, so a ±10 V set point directly modulates the internal current loop without protocol conversion. This arrangement supports systems that use conventional analog command signals rather than a serial motion interface. It is part of the DIAX04 controller family, which standardizes dimensions and backplane communication for modular assemblies. Thermal management is handled by a built-in air blower that draws cabinet air across the heat sink to maintain drive temperature. The product is part of Line 04, and the revision status is 2.

The current loop remains stable during steep load transients, supporting consistent motor response under changing demand. The dedicated airflow channel created by the blower directs cabinet air across the heat sink without relying on external cabinet fans. By accepting a direct analog set-point, the controller remains compatible with existing PLC output cards while synchronizing with the internal bus used throughout a DIAX04 rack. This helps the unit fit into machine layouts that still use analog command hardware for axis control.
