Product Description:
The HDS03.2-W100N-HS91-01-FW is a drive controller produced by Bosch Rexroth Indramat and assigned to the HDS Drive Controllers series. In a multi-axis automation cell, the unit manages DC bus power and coordinates servo motion through its onboard control electronics. By acting as the central axis module, it converts commands from higher-level PLCs into current and velocity references for synchronized positioning and speed regulation. Closed-loop command handling lets connected axes respond consistently during acceleration, steady-state operation, and coordinated changes in direction. This arrangement supports repeatable motion for tooling, material handling, and general machine automation without spreading control functions across separate modules.
Communication between the controller and axis drives is handled over the SERCOS optical ring, which transfers setpoint, feedback, and diagnostic data on the same fiber. The power section is rated for a continuous output of 100 A, which is the maximum current the module can sustain without derating. Thermal stability is maintained by a built-in air blower that routes airflow across the heat sink surfaces, so no external cabinet fan is required for this function. The unit is part of the DIAX04 drive family, and it matches the shared DC bus arrangement used across that platform. The product is part of Line 03 in the series, which marks the design revision used for this controller. Because command and status data travel on the same fiber path, the motion network remains organized within the cabinet.
The product type is HDS Drive Controller, so control electronics and power electronics are combined in one housing. The controller is Version 2, indicating the revision supplied for this model. It follows the mounting pattern and parameter structure used across the HDS Drive Controllers series, which supports consistent installation in modular multi-axis cabinets. Integrated control and power sections reduce the need for separate controller cards inside the same housing footprint.
