Product Description:

The HDS03.2-W100N-HS94-01-FW is an axis controller module produced by Bosch Rexroth Indramat for the HDS Drive Controllers series. It is intended for industrial automation tasks where coordinated multi-axis motion is required, such as packaging units, machining centers, or material-handling cells. By converting high-level motion commands into precisely regulated motor currents, the module synchronizes speed, torque, and position loops so each mechanical axis follows the commanded profile. In these systems, the controller helps maintain axis-to-axis coordination during speed changes and load variations so commanded motion remains stable throughout the machine cycle.

Communication takes place over the fiber-optic SERCOS interface, giving deterministic timing and full-duplex data exchange with the master controller. The fiber-optic link is used for cyclic command values, status data, and synchronized timing between the controller and the higher-level motion system. Membership in the DIAX04 family means the unit plugs into a common backplane that distributes DC bus power and system diagnostics across the rack. Its power section is rated for 100 A, providing the current needed for rapid accelerations and heavy dynamic loads on connected servo or spindle axes. A built-in air blower forces cooling air across the heat sink, keeping semiconductor temperatures within limits without external fans. The unit is part of Line 03 in the series.

The drive controller is Version 2, and it uses updated processing resources for faster current control loops during dynamic operation. Its classification as an HDS Drive Controller confirms mechanical and electrical compatibility with supply modules and auxiliary cards in the same rack. That compatibility supports compact multi-axis layouts while keeping the electrical interfaces consistent throughout the system. Because it works with supply and auxiliary modules in the same rack, power distribution and control functions can be organized across dedicated modules.
