HDS03.1-W075N-HT11-01-FW
The HDS03.1-W075N-HT11-01-FW is a modular drive controller manufactured by Bosch Rexroth Indramat for the HDS Drive Controllers series. Designed to sit in a rack beside matching power supplies and I/O modules, it converts command data into drive-ready current and voltage signals for the motor control loop. It closes the motor control loop by turning controller commands into regulated electrical output that follows changing motion demands. That control role lets the unit regulate torque, speed, and position on a single axis rather than serving as a passive interface card. In industrial production lines, it can support tool positioning, conveyor indexing, and coordinated robot motion where repeatable axis response is required during continuous machine cycles.
Command exchange is performed over the SERCOS optical fiber interface, permitting deterministic communication with motion controllers at data rates up to 16 Mbaud. Within the controller cabinet, the unit belongs to the DIAX04 family, so it matches the mechanical layout and module arrangement used in that rack platform. Thermal regulation relies on a built-in air blower that draws air through the heatsink, so no external ducting is required around the module body. The power section is rated for 75 A, giving the controller the capacity for continuous operation with compatible synchronous or induction motors in medium-duty and higher-load axis applications.
The controller is part of Line 03, which places it in the third design line for this product platform. It is Version 1, indicating the initial release of this hardware configuration. The module integrates with companion supply units, feedback cards, and mains filters that share the same enclosure format, helping preserve cabinet spacing and internal airflow. Because the housing and front access remain consistent with the rest of the rack system, the controller fits cleanly into multi-module drive cabinets where organized wiring and cooling space matter.
