HDS05.2-W300N-HA34-01-FW
The HDS05.2-W300N-HA34-01-FW is a drive controller built by Bosch Rexroth Indramat in the HDS Drive Controllers series. It operates as the central power module in multi-axis automation racks, converting shared DC link energy into regulated three-phase outputs for individual servo motors. The regulated outputs let each axis receive commanded motor current rather than unregulated supply power, which supports controlled acceleration and deceleration. This role supports precise motion control for packaging equipment, material-handling robots, and machine-tool axes that require coordinated positioning and reliable speed regulation.
The command channel uses an analog interface, so velocity or torque references are applied as differential voltages that the controller converts into PWM signals for the power stage. Within the DIAX04 family, this model occupies a high-current position, and its thermal management relies on a built-in air blower that moves cooling air through the heat sink without external ducting. The power electronics are rated for a continuous output of 300 A, allowing the controller to drive large synchronous or induction motors under sustained load. Overcurrent detection, short-circuit monitoring, and field-weakening supervision are implemented in hardware to protect the drive and connected motor components during demanding duty cycles.
The unit is part of line 05, which uses the mechanical footprint and connector orientation assigned to this design line. It is an HDS Drive Controller and is intended for use with matching HMS or HVR power supplies in multi-axis systems. In that arrangement, the controller serves as the regulated output stage between the shared supply section and the connected motor axes. Its placement in the rack keeps the power path concentrated inside the drive assembly and supports coordinated axis response during speed and position changes. This layout also avoids the need for separate external power-conversion hardware for each connected axis.
