Product Description:

The HDS03.2-W075N-HS11-01-FW is a drive controller produced by Bosch Rexroth Indramat for the HDS Drive Controllers series. Installed in an automation rack, it manages power delivery to servo axes so that machinery follows commanded torque or velocity references from a central motion processor. By converting the shared DC bus energy into regulated three-phase output, the unit maintains precise motor behavior required in industrial handling, packaging, and machining cells. This role lets the controller support rapid acceleration, stable running speed, and repeatable response to changing loads during coordinated axis motion.

Its command layer communicates through the fiber-optic SERCOS interface, delivering deterministic telegram cycles to CNC or PLC masters with synchronized timing across the machine. Because it belongs to the DIAX04 controller family, the module shares backplane mechanics with other axes in the same rack, which helps keep cabinet integration consistent in multi-axis systems. Thermal regulation is handled by a built-in air blower that directs cabinet air across the heatsink and prevents semiconductor overheating without external ducting. The power stage supports a continuous motor armature current of 75 A, letting the device run medium-to-high torque motors at rated load without derating. This combination supports continuous operation where several controlled axes must respond together under changing process demands.

The module is an HDS Drive Controller and is part of line 03, so its enclosure dimensions and connector layout follow the third-generation rack pattern used across current DIAX cabinets. The unit is version 2. Its internal cooling arrangement helps the drive sustain its rated output even when neighboring axes share the same DC bus in a densely packed enclosure. The layout is intended for rack installation, where alignment of power and signal connections is important for orderly system assembly.
