HDS02.1-W040N-HS27-01-FW
The HDS02.1-W040N-HS27-01-FW is a drive controller manufactured by Bosch Rexroth Indramat for the HDS Drive Controllers series. It acts as the motion node inside DIAX modular racks, supplying regulated motor current and closed-loop command processing to servo axes used in material handling, machining, and packaging lines. In multi-axis systems, it interprets motion commands from the higher-level control and regulates the connected motor so speed, torque, and position remain accurate during operation. This arrangement allows one rack to support coordinated axis control while keeping power conversion and feedback handling inside the drive system.
Communication with the host PLC takes place over the fiber-optic SERCOS interface, which enables deterministic exchange of set points and feedback data across several drives on a single ring. The power section is rated for a continuous output of 40 A, allowing it to energize medium-frame synchronous or induction motors without external boosters. Thermal regulation is handled by a built-in air blower, which moves cabinet air across the heat sink through a self-contained cooling path. The controller belongs to the DIAX04 family, so it shares slot dimensions and encoder evaluation methods with other modules in that platform. In the type code, it is identified as an HDS Drive Controller, and that classification places it in the axis-control section of the rack rather than in the supply stage.
The unit is part of Line 02, which places it in the second design line of this product group. It is also Version 1 and is intended for use with matching HMS power supplies in HDS rack systems. Because power is provided by the companion supply module, the controller focuses on axis regulation and output control within the rack. The module mounts in a shared backplane arrangement, and its connector layout supports organized integration with adjacent analog or digital axis modules. Its profile height and connector orientation help maintain a consistent cabinet layout when several drive sections are installed in the same enclosure.
