HDS03.2-W100N-HS73-01-FW
The HDS03.2-W100N-HS73-01-FW is a modular axis inverter built by Bosch Rexroth Indramat for the HDS Drive Controllers series. Installed in a multi-axis rack, the unit closes current and velocity loops for servo and spindle motors, translating digital motion commands into regulated three-phase output. By regulating motor current against incoming commands, it supports stable torque production on coordinated axes during positioning and speed-controlled operation. That behavior is important on machine tools, handling systems, and production lines where several axes may need to accelerate, decelerate, and settle without drift.
The controller exchanges real-time setpoints and status over the SERCOS fiber-optic ring. This deterministic bus serves as the drive’s command interface, allowing synchronized position data and diagnostics to circulate among all axes with consistent timing. Within the DIAX04 family, the device matches common backplane dimensions and connector layouts, which helps it fit established rack assemblies without changing the basic cabinet arrangement. Thermal management is handled by a built-in internal air blower that draws cooling air across the heat sink without external ducting. The fiber-optic link also supports coordinated motion sequences in which multiple modules respond to the same timing reference. The power stage sustains a continuous output of 100 A, enabling the module to energize large synchronous or induction motors at nominal DC-bus voltage while maintaining stable output under continuous demand.
The unit is classified as an HDS Drive Controller and belongs to Line 03. It is listed as Version 2, which distinguishes this build within the product line. These identifiers place the controller within the rack-based HDS range used for SERCOS motion systems. They are the key identification details provided for this unit.
