HDS03.2-W100N-HS66-01-FW
The HDS03.2-W100N-HS66-01-FW is a drive controller produced by Bosch Rexroth Indramat and assigned to the HDS Drive Controllers series. Within a multi-axis cabinet, it regulates power to servo drives and coordinates motion through the series' common power bus. The unit converts commanded velocity or torque profiles into controlled three-phase outputs so connected motors follow programmed trajectories in machine tools, handling robots, and packaging lines. It acts as the power and control stage for servo axes, helping connected motors track acceleration, speed, and torque commands during synchronized machine cycles.
This controller exchanges cyclic setpoints and feedback over a fiber-optic ring that complies with the SERCOS protocol, allowing deterministic coordination with PLCs and neighboring axes. Its power stage is rated for 100 A, so compatible axes can draw that continuous current without external boosters. Thermal management is handled by a built-in air blower, which pulls cabinet air through heat-sink channels to keep semiconductor temperatures within limits. This cooling method removes the need for separate ducting and keeps the housing layout compact inside the cabinet. The unit belongs to the DIAX04 family, so it shares mechanical dimensions and backplane connections with related modules in the same platform.
The controller is Version 2. Within the DIAX04 lineup, it is part of Line 03, which identifies the matching power section arrangement used for this design group. This revision refines the internal gate-drive electronics and adds more diagnostic detail for fault reporting. Its mounting pattern, encoder channel, and network interface follow the layout used across compatible platform modules, which supports straightforward integration in a multi-axis cabinet. The communication setting is fixed for SERCOS operation, so the unit is intended for use on that optical network rather than alternate command interfaces.
