HDS02.1-W040N-HA13-01-FW
The HDS02.1-W040N-HA13-01-FW is a digital drive controller manufactured by Bosch Rexroth Indramat as part of the HDS Drive Controllers series. Within a multi-axis system, it serves as the power and control stage for AC servo motors, coordinating velocity, torque, and diagnostic data for each axis. By converting DC bus energy from a central supply into regulated three-phase output, the controller supports precise closed-loop motion in packaging lines, printing machinery, and automated assembly stations. It regulates motor output in real time so axis speed and torque follow the command signal during acceleration, steady travel, and stopping. This arrangement lets a central supply feed multiple axes while each controller manages the motor current for its assigned channel.
Its continuous output capability is rated at 40 A, which is the maximum motor phase current the unit can supply without derating. Command signals enter through an analog interface, allowing velocity or torque setpoints to be delivered as standardized voltage levels from a PLC or motion card. The controller belongs to the DIAX04 family, so it shares backplane dimensions and communication buses with other axis modules used in the same system. Thermal management is handled by a built-in air blower that draws air through the heat sink to maintain safe component temperatures at full load. The unit is Version 1, indicating the first design iteration of this controller. This helps the drive remain stable during extended duty cycles in enclosed control cabinets.
In the product code, the designation Line 02 shows that this controller conforms to the second mechanical footprint used throughout the platform. It is categorized as an HDS Drive Controller, so its role is servo axis regulation rather than supplying the shared DC bus. The module is intended to work with cabinet layouts that use matching drive components, and its footprint keeps mounting points consistent across compatible power classes. This separation is typical of modular DIAX systems, where individual axis controllers draw energy from a common DC bus instead of generating it locally. The result is a drive layout in which power conversion and axis regulation are divided between dedicated modules.
