HDS05.2-W300N-HS12
The HDS05.2-W300N-HS12 is a drive controller manufactured by Bosch Rexroth Indramat for the HDS Drive Controllers series. It serves as a closed-loop power stage between servo motors and higher-level motion or PLC platforms, handling axis regulation, current modulation, and fault monitoring in industrial automation lines that require coordinated multi-axis movement. When used as an HDS Drive Controller, the unit supports precise response to commanded motion profiles and keeps motor control, status handling, and protective functions concentrated in one drive section. This arrangement allows the central control system to supervise motion while the drive manages the electrical output required by the motor.
This model exchanges setpoints and feedback through the SERCOS optical interface, allowing deterministic cyclic data traffic between the drive and the master control. It belongs to the DIAX04 controller family, so its encoder evaluation and connector layout match other DIAX04 components. The unit can deliver up to 300 A of continuous output current, enabling it to support large torque motors on demanding axes. Heat generated by switching losses is removed by a built-in air blower, so cooling air moves through the heat sink channels without external ducting. The designation Line 05 identifies the mechanical frame size and indicates that the mounting points follow the 05 drilling pattern within the HDS range.
The unit is Version 2, which marks the hardware revision used for this model. This revision uses updated gate drivers and expanded diagnostic codes, improving status reporting and internal control handling during operation. It occupies the power module tier and pairs with supply units that use the same DC bus voltage. The front section accepts the optical communication loop, while the rear groups the motor, brake, and feedback terminations to keep wiring paths short in crowded cabinets.
