Product Description:

The HDS05.2-W300N-HT12-01-FW is a drive controller produced by Bosch Rexroth Indramat and assigned to the HDS Drive Controllers series. As a modular axis module, it regulates current and velocity loops for synchronous or induction motors in multi-axis automation lines. Integrated gating and feedback channels let it serve as the power stage between a higher-level motion controller and the machine mechanics. That control structure helps the axis respond quickly to changing load conditions during acceleration, deceleration, and holding phases. It supports closed-loop torque and position control in packaging, machining, and material-handling cells.

This version belongs to the controller family DIAX04, so it plugs into a common supply unit in that rack and shares the DC bus and fiber-optic command ring. Command data arrives over the SERCOS interface, which exchanges real-time setpoints optically and helps resist electrical noise in industrial cabinets. The product line code is 05, and the unit is revision 2. A built-in internal air blower moves cabinet air through the heatsink to control thermal load during extended operation. The power stage is rated for a continuous motor current of 300 A, which suits high-torque axes such as spindle drives and other demanding servo applications.

In normal service, the unit functions as an HDS Drive Controller in a modular rack with neighboring axis modules. Cabinet airflow across the heatsink keeps semiconductor temperatures stable, while the shared DC bus lets regenerated energy move to adjacent modules instead of remaining only at one axis. The optical command network helps prevent ground loops and supports deterministic cycle times during synchronized multi-axis motion. This layout allows coordinated axes to exchange power and command data within the same rack structure.
