HDS05.2-W300N-HA21-01-FW
The HDS05.2-W300N-HA21-01-FW belongs to the HDS Drive Controllers series from Bosch Rexroth Indramat. As a modular current-controlled drive unit, it links servo drives to centralized numerical or PLC systems and regulates motor torque and velocity inside multi-axis racks. In factory automation, the controller serves as the power and feedback junction between the motion CPU, the drive bus, and connected synchronous or asynchronous motors. Because regulation is handled in the controller, the motor can respond quickly to command changes and load disturbances during repetitive positioning and spindle-duty cycles.
Command data reach the unit through an analog interface, so motion references are converted from voltage or current levels into internal setpoints without digital fieldbus hardware. This arrangement allows conventional analog command sources to be used where simple reference signaling is preferred. The controller is part of the DIAX04 platform, which uses a common backplane arrangement with other DIAX modules in multi-axis systems. It can supply continuous motor current up to 300 A. Heat from conduction and switching losses is removed by a built-in air blower, which supports thermal management without external cabinet ducting and allows compact rack installation.
The unit is part of Line 05, which indicates its place in the DIAX mechanical and electrical design line. It is listed as Version 2, which uses second-generation control electronics with extended diagnostics and faster current loops. The controller is intended for modular rack installation, where neighboring supply and control modules share the DC bus and system communication path. Extended diagnostics provide clearer operating status during machine operation, and the faster control response supports stable torque delivery during acceleration, speed regulation, and position control.
