HDS05.2-W300N-HT05-01-FW
The HDS05.2-W300N-HT05-01-FW is a modular drive controller produced by Bosch Rexroth Indramat. Installed in drive racks, it converts DC bus energy into controlled three-phase output for servo and main spindle axes on automated machinery. By managing current and feedback in real time, the controller provides precise speed, torque, and position control for packaging lines, printing presses, and material-handling gantries. This supports coordinated motion where axis response must remain stable during changes in load, speed, and direction. Its form factor matches other modules in the platform, allowing multiple axes to share a common power supply section.
In operation, the unit provides a continuous phase current of 300 A, which supports high torque demand during acceleration and punching cycles. Command data arrive over the SERCOS fiber-optic ring, so multiple axes can share the same time base for coordinated moves. Heat is removed by a built-in air blower, and the internal fan circulates enclosure air across the heat sink without external ducting. The controller belongs to the DIAX04 family, which uses a standardized connector layout and common diagnostic handling across the rack. Its functional class is an HDS Drive Controller, so current loops and protective logic are handled directly on the module. This arrangement keeps the power stage and motion control functions in the same unit rather than shifting them to a separate converter.
The code 05 identifies the product line within the model designation. The following 2 marks the second version in that designation. It is part of the HDS Drive Controllers series, where rack-mounted modules are used with separate supply sections in multi-axis systems. The remaining characters in the model code separate power, cooling, and option selections within the same naming format. This coding structure keeps identification concise while separating the major electrical and mechanical options in the model number.
