Product Description:

The HDS05.2-W300N-HS32-01-FW is a servo drive controller manufactured by Bosch Rexroth Indramat for the HDS Drive Controllers series. In multi-axis industrial automation, the unit supplies regulated power to synchronous or induction motors and converts high-level motion commands into controlled motor current. This allows the drive to close torque and speed loops for accurate positioning and coordinated movement in gantries, packaging stations, transfer systems, and other automated machine sections. Because the power stage and control section work together inside one module, the drive can respond quickly to changing load conditions during acceleration, deceleration, and synchronized motion. It also helps protect the motor and machine mechanics by regulating current delivery during dynamic operation.

Communication is handled through the SERCOS fiber-optic ring, which supports real-time data exchange and a simple daisy-chain layout. Fiber-optic communication also helps reduce susceptibility to electrical noise in cabinets that contain high-power switching equipment. The hardware is part of the DIAX04 family, so its backplane connections, feedback channels, and supply rails match other DIAX04 modules used in the same rack. The unit has a rated current of 300 A, which is the continuous RMS motor phase current available before thermal derating begins. Cooling is provided by a built-in air blower that moves cabinet air across the heat sink and power semiconductors, so no external fan assembly or liquid cooling circuit is required. This airflow path supports stable thermal operation during long duty cycles at high current demand.

The unit is released as Version 2. It is assigned to Line 05, which corresponds to the module height and connector orientation used within the drive stack. The product is classified as an HDS Drive Controller. Version and line codes are used to distinguish this module from other members of the range that differ in size or layout. This classification indicates that the unit serves as the drive power and regulation stage rather than as a standalone power supply module.
