Product Description:

The HDS05.2-W300N-HS36-01-FW is a digital drive controller manufactured by Bosch Rexroth Indramat for the HDS Drive Controllers series. It supplies regulated current to Indramat servo motors and exchanges real-time motion commands with higher-level control systems, so it fits coordinated multi-axis machine tools, printing lines, and material-handling cells. By converting bus commands into precise phase currents, the unit closes the torque loop at the drive and improves dynamic accuracy. It can serve as the power stage for demanding feed axes that require fast current response and repeatable motion.

This controller communicates over the SERCOS optical ring, so parameter data and synchronous setpoints travel on a deterministic 2 Mbps channel that minimizes motion-profile jitter. A continuous output of 300 A gives the module enough headroom to accelerate large synchronous motors, while peak current is internally limited by monitoring circuits that protect cabling and motor windings. Thermal energy is removed by a built-in air blower, permitting cabinet installation without external ducts. The optical interface also reduces susceptibility to electrical noise inside high-power cabinets. The unit belongs to the DIAX04 platform, where it shares a common backplane, auxiliary supply, and diagnostic structure with related modules.

This model is classified under Line 05, which corresponds to the 22 kW power section size and compatible supply modules. Hardware Version 2 uses revised gate drivers that allow higher switching frequencies than the original release. Higher switching frequencies can improve current regulation during demanding low-speed or high-dynamic operation. When paired with synchronous motors equipped with compatible feedback, the controller can execute position loops inside the drive, freeing the central PLC for supervisory logic. Mounting holes align with the DIAX rail pattern, and built-in status LEDs show operating state, error number, and network activity.
