HDS02.1-W040N-HA25-01-FW
The HDS02.1-W040N-HA25-01-FW drive controller is produced by Bosch Rexroth Indramat and belongs to the HDS Drive Controllers series. It serves as an axis amplifier inside multi-axis racks, converting shared DC bus voltage into a regulated three-phase output for synchronous or induction motors. This role allows the unit to support accurate speed and torque control in packaging, printing, and material-handling systems where coordinated motion is required. By regulating motor current at the rack level, the controller helps connected axes respond smoothly to changing load demands during normal operation.
In the DIAX04 platform, the module uses an ANALOG command channel, so references are supplied as ±10 V signals rather than digital network messages. This arrangement works well with legacy motion cards that issue direct voltage commands for speed or torque control. Its power stage can deliver a continuous output of 40 A, which suits mid-range motor loads while preserving thermal headroom in the cabinet. Cooling is provided by a built-in air blower that moves cabinet air across the heat sink, so external ducting is not required. The airflow path supports stable operation when the controller is installed alongside other rack modules in enclosed automation panels.
The controller is part of Line 02 and it is a Version 1 unit. It is intended for installation in a shared DC bus rack, where multiple axes can operate from a common supply section without separate power conversion at each motor. The module fits applications that need regulated motor current, steady torque response, and compatibility with analog reference wiring. Its rack-based format also keeps power and control functions in a single drive assembly, which helps maintain an orderly system layout for multi-axis equipment.
