Product Description:

The HDS05.2-W300N-HS38-01-FW is a single-axis drive controller manufactured by Bosch Rexroth Indramat for the HDS Drive Controllers series. It supplies regulated DC power and closed-loop control to servo motors, allowing coordinated positioning and velocity control in automated machining centers, assembly cells, and material-handling stations. Motion commands reach the unit through the optical SERCOS interface, providing time-deterministic communication with CNCs and PLCs. In applications that require repeatable axis motion, the controller adjusts motor current in response to command and feedback data so speed and position remain controlled throughout the cycle.

As part of the DIAX04 controller family, it shares mounting dimensions with other modules in that platform, which helps organize multi-axis cabinet layouts. The power stage is rated for a continuous output of 300 A, so it can drive large torque motors during sustained acceleration and other high-load operating periods. This output capacity makes it suitable for axes that demand strong continuous torque instead of only short peak bursts. Thermal energy from the power electronics is removed by a built-in air blower, which avoids the need for external ducting while supporting stable internal temperatures. The line code 05 identifies the mechanical frame size and connector arrangement used for this current class within the series.

The controller is released as hardware revision 2. This revision includes updated gate-driver circuitry and diagnostic behavior compared with the initial release. The added diagnostic coverage improves status monitoring during operation and helps the control system react to faults more quickly. Its functional designation as an HDS Drive Controller means that it handles both power conversion and digital axis supervision rather than serving only as a supply module. That arrangement allows one unit to manage motor current delivery and motion-related control tasks within the same axis package.
