Product Description:

The HDS04.2-W200N-HS12 is a drive controller from the HDS Drive Controllers series by Bosch Rexroth Indramat. In industrial automation, it supplies regulated power to servo and spindle motors, closing the control loop between a motion controller and the mechanical axis. The module interprets real-time command words, adjusts output current instantly, and isolates the machine PLC from high-energy switching. By separating these tasks, it helps maintain stable torque delivery during acceleration, deceleration, and position holding on demanding axes. It is used in multi-axis equipment where repeatable motor response is required across changing loads.

Communication with higher-level motion hardware takes place over SERCOS, a deterministic digital bus that transmits position setpoints and feedback data at fixed intervals. Fixed-cycle data exchange supports synchronized responses between the controller and the central motion system. The controller belongs to the DIAX04 family and uses the same rack-based format as other modules in that platform. Thermal management is handled by a built-in air blower, eliminating the need for external cabinet ventilation ducts. The module is classified in Line 04. Its power stage can deliver 200 A continuously, allowing it to drive large torque motors without derating. That current capacity supports rapid acceleration on heavy axes and spindles with high startup demand.

Within the series, the product is identified as HDS Drive Controller, and its design is marked 2, indicating the second revision inside the HDS04 line. The controller is intended for rack-mounted drive systems where power conversion and motion regulation are handled in a dedicated module. Its format suits installations that already use HDS-based axis control hardware. In these systems, the drive operates as the power stage between the shared supply and the connected motor.
