HDS05.2-W300N-HA10-01-FW
The HDS05.2-W300N-HA10-01-FW is a modular drive unit produced by Bosch Rexroth Indramat for the HDS Drive Controllers series. In multi-axis machinery, this unit converts DC bus energy from a supply module into controlled three-phase power for servo motors, enabling coordinated motion, positioning, and process control on packaging lines, machine tools, and material-handling systems. It serves as the final power stage, interfacing with a higher-level motion controller and field feedback to maintain precise current and velocity loops in industrial environments. The modular format allows the controller to operate as one axis within a larger shared-bus drive system.
Command inputs are accepted through an analog interface, so velocity or torque references arrive as ±10 V signals that the controller digitizes for its internal loops. The unit belongs to the DIAX04 family and shares a common backplane and diagnostic structure with other axis modules. Thermal management is handled by a built-in air blower that draws cabinet air across the heat sink without the need for external ducting. The power section can deliver up to 300 A of motor current, making it suitable for high-torque axes such as main spindles or gantry drives. This controller combines current regulation, velocity control, and fault monitoring in one housing, so external control hardware can focus on motion commands rather than power conversion.
The controller is Version 2, which identifies the second design iteration of this model. It is part of Line 05 in the HDS range, placing it above lower-current variants. The control section supervises gate firing sequences and monitors operating faults during axis operation. That oversight helps the drive respond quickly to changing load conditions on large servo axes. Its layout also keeps the electrical and thermal functions within the same module footprint used by companion units.
