Product Description:

The HDS03.2-W100N-HS47-01-FW is a drive controller manufactured by Bosch Rexroth Indramat and supplied within the HDS Drive Controllers series. In an automated cell, it regulates the current, speed, and position loops for connected servo axes, taking motion commands from a higher-level CNC or PLC and converting them into precisely timed switching patterns for the associated power section. The unit mounts on a shared DC bus rail next to HVE power supplies and other HDS modules, which helps organize cabinet layout in machine tools, material-handling lines, and packaging equipment where several axes operate from the same drive assembly.

The power electronics are engineered for a continuous output of 100 A, which is the maximum motor phase current the unit can deliver without thermal derating during steady operation. Command and feedback data reach the controller through the fiber-optic SERCOS interface, which provides deterministic timing and electrical isolation from noisy plant environments. The controller is part of the DIAX04 family, which uses a common module format for multi-axis racks and helps keep neighboring components mechanically consistent. Waste heat is expelled by a built-in internal air blower, keeping heat sink temperatures within limits without requiring external ductwork or separate cooling accessories.

The unit is part of Line 03, which indicates the physical frame height and mounting hole pattern used in the third size class. It is Version 2, matching the later parameter sets and diagnostics used by newer SERCOS masters. The designation HDS Drive Controller indicates that this module provides axis control rather than power supply functions within the wider product line. It does not include an integrated power supply or brake resistor, so those functions are handled by separate system modules elsewhere in the drive arrangement.
