HDS03.1-W100N-HA21-01-FW
The HDS03.1-W100N-HA21-01-FW drive controller is manufactured by Bosch Rexroth Indramat as part of the HDS Drive Controllers series. The unit functions as the central power stage in multi-axis servo systems, taking velocity or torque references from higher-level motion processors and feeding controlled current to connected motors for precise industrial automation. By modulating the shared DC bus, it supports coordinated movement across gantry, spindle, and auxiliary axes on production machinery. The controller is suited for applications where synchronized acceleration, deceleration, and holding torque must be maintained across several machine motions.
It receives command signals through an analog interface, so the drive interprets ±10 V references from CNC or PLC hardware without additional fieldbus cards. The continuous output capability is 100 A, enabling it to energize medium-frame servomotors while maintaining regulated current loops. Thermal management relies on a built-in air blower, which moves cabinet air across the heat sink and eliminates the need for external ducts. Compatibility with the DIAX04 controller family allows the module to share a common DC bus and diagnostic structure with other axes in the same rack. The unit is part of Line 03, which matches the connector layout used by third-generation DIAX power sections.
The unit is classified as an HDS Drive Controller and is listed as Version 1. A dedicated command interface keeps scaling constants inside the controller, so external devices can send reference values without added signal conditioning. This keeps the control structure compact in cabinets where separate signal conversion hardware is not desired. Protective shutdown logic is integrated into the drive, allowing it to regulate motor current during normal operation and interrupt output when abnormal conditions are detected.
