HDS03.1-W100N-HA23-01-FW
The HDS03.1-W100N-HA23-01-FW is a modular axis drive controller built by Bosch Rexroth Indramat for the HDS Drive Controllers series. It supplies regulated DC bus energy and precise current commands to servo motors used in assembly lines, packaging systems, and material-handling cells. By receiving motion references from a higher-level control and closing the current and velocity loops locally, the unit keeps each mechanical axis on its programmed trajectory. Because the power stage and regulation functions are combined in one housing, the drive can serve as a dedicated axis module within a larger cabinet-based motion system.
The command stage accepts an analog ±10 V reference, translating that input into proportional inverter current for real-time torque control. A continuous capability of 100 A is the maximum phase current available to the connected motor under rated conditions. Thermal stress is managed by a built-in air blower that draws cabinet air across the heat sink, eliminating the need for external ducting. This arrangement allows the controller to respond directly to analog command signals from external motion electronics. Within the DIAX04 platform, the module shares back-plane connectors, diagnostic codes, and parameter maps so it can be used in mixed multi-axis racks. The unit is part of Line 03, which marks the third design line.
The module is Version 1, which uses the current parameter structure and diagnostic message set for this drive type. It is classified as an HDS Drive Controller and works with matching supply and feedback modules in coordinated motion systems. Local regulation of motor current and speed helps the axis respond quickly to command changes while keeping the main control functions inside the drive. It is intended to operate as one axis module within a larger drive assembly rather than as a standalone machine controller. This layout supports synchronized motion in systems where several axes run together on the same DC bus.
