HDS05.2-W300N-HS78-00-FW
The HDS05.2-W300N-HS78-00-FW is a modular drive controller manufactured by Bosch Rexroth Indramat for the HDS Drive Controllers series. In multi-axis automation racks, it regulates current and velocity loops for servo motors so coordinated positioning and speed control can be handled from a central motion controller. By converting incoming DC bus energy into precisely timed three-phase outputs, the unit serves as the power stage for demanding motion tasks in metal-cutting equipment, packaging lines, and material-handling systems. During operation, the control section helps the motor follow commanded acceleration and speed changes with stable response. Its rack-based format also allows it to operate alongside matching supply and interface modules in the same cabinet.
For deterministic command transfer, the controller uses the SERCOS optical fiber interface, which supports cyclic setpoint updates and status exchange over a common ring. Inside the drive cabinet, membership in the DIAX04 platform means its communication, power, and cooling connections align with compatible modules. Continuous motor demand can be served up to 300 A, so the inverter section can supply high current for large servo axes. Thermal stability at that load is maintained by a built-in internal air blower that moves cabinet air through the heat sink channels instead of depending on external fans. The housing is assigned to Line 05, which indicates the physical size and slot spacing used in the rack.
The unit is Version 2. This version identifies the product generation used for the controller and separates it from earlier releases in the same family. Because the drive shares the same rack concept as related axis modules, it supports a consistent wiring layout and organized placement within a multi-axis system. The controller is suited for applications that need high output current, fiber-optic communication, and enclosed-cabinet cooling without adding separate external fan assemblies.
