Product Description:

The HDS04.1-W200N-HS27-01-FW is a digital drive controller built by Bosch Rexroth Indramat and assigned to the HDS Drive Controllers series. Within a multi-axis drive system, the module supplies regulated DC bus power to one servo axis while responding to velocity and torque commands from higher-level motion processors. In machining centers, material handling lines, and packaging equipment, it works as the power stage that converts serial control data into the motor current needed for accurate axis movement and stable dynamic response. Its role is limited to a single axis, which allows each channel in the rack to be matched to the mechanical load it drives.

The controller exchanges real-time motion data over the SERCOS fiber-optic interface, which carries both drive parameters and cyclic setpoints at deterministic update rates for synchronized motion control. As part of the DIAX04 family, it mounts on a common supply rail and shares the rack DC link with companion drives, supporting compact multi-axis cabinet layouts. Continuous thermal management is handled by a built-in air blower that pulls air through the card cage, so no external cabinet fan is required for the module itself. The nominal output capability reaches 200 A, allowing the unit to drive large synchronous or induction servo motors without dropping below its stated current class during normal operation.

The controller is Version 1, which identifies the product revision used for this model. The designation Line 04 places it in the fourth design line of the range and indicates the connector arrangement used by the unit. That line assignment also matches the bus-voltage compatibility and performance class associated with this controller type. These identifiers distinguish the unit within the product range without changing its function as a single-axis power stage in a shared drive rack.
