HDS04.2-W200N-HA29-01-FW
The HDS04.2-W200N-HA29-01-FW drive controller is manufactured by Bosch Rexroth Indramat and belongs to the HDS Drive Controllers series. It functions as an axis amplifier between a motion processor and an electric motor, converting command signals into controlled three-phase output for automation cells such as gantries, packaging lines, and machining centers. By combining regulation electronics with power switching hardware in one unit, the controller supports closed-loop motor control while helping keep cabinet layouts compact. This arrangement lets the controller respond quickly to command changes while maintaining stable drive behavior during acceleration and load changes.
The controller processes setpoints through an analog command interface, so velocity and torque references arrive as differential voltage signals instead of network data. Because the reference enters as a voltage signal, the unit fits systems that use analog motion commands rather than a digital communication bus. It is part of the DIAX04 family and uses a shared backplane arrangement for multi-axis rack installation. Thermal management is handled by a built-in air blower, which moves cabinet air across the heat sink without external ductwork. The power stage has a continuous rating of 200 A, and the unit is part of Line 04, which identifies this design line in the series.
The unit is Version 2. It contains current loop, resolver decoding, and fault logic functions required for closed-loop operation, reducing the need for external signal-processing hardware. Those internal functions allow the controller to supervise motor operation and react to abnormal conditions during running. Standardized interfaces help it mate with matching supply, feedback, and auxiliary modules in the same rack. It can therefore be integrated into larger axis groups without changing the basic rack concept.
