HDS03.2-W100N-HA11-01-FW
The HDS03.2-W100N-HA11-01-FW is a modular axis module produced by Bosch Rexroth Indramat. Installed in a DIAX04 rack, it works as the power stage for servo or spindle motors in packaging, printing, and material-handling equipment. The module follows reference signals from a separate command card and converts DC-bus energy into controlled motor current for accurate torque and speed response. That arrangement lets the drive react quickly to changing load conditions while the higher-level controller handles motion sequencing. Its shared bus arrangement also helps compact multi-axis cabinet layouts by allowing several axes to operate from the same power structure.
This controller delivers up to 100 A of continuous output, which supports high-torque acceleration during sustained operation. It receives reference commands through an analog ±10 V interface, making it suitable for systems that use legacy motion PLCs or stand-alone analog control cards. Thermal management is handled by an internal air blower that moves cabinet air across the heat sink, so no external ducting is required. The current capacity is useful on axes that must start heavy loads repeatedly or maintain force at low speed. Because the blower uses cabinet air, the module can be integrated without separate cooling ducts or remote fan assemblies.
The unit is part of Line 03 and uses Version 2 hardware for this power section. The function group is HA11, which corresponds to the analog command version of the module. It belongs to the HDS Drive Controllers series, where the rack format supports close spacing with matching power components. The rack format also keeps bus alignment consistent across adjacent modules. Regenerated energy can return to the shared supply path instead of being dissipated only as heat. This layout suits systems in which one axis decelerates while another accelerates, which helps reduce wasted heat inside the cabinet.
