HDS03.1-W100N-HT02-01-FW
The HDS03.1-W100N-HT02-01-FW is a drive controller manufactured by Bosch Rexroth Indramat and supplied within the HDS Drive Controllers series. It is used as an axis module in multi-axis racks, where it manages power conversion, torque commands, and status feedback for industrial servo motors. In automated machinery, the unit closes the electrical loop between the central motion processor and an individual mechanical axis so that velocity, position, and acceleration profiles are carried out with deterministic timing. This format supports rack-based motion systems that need one dedicated controller for each driven axis. Because it works inside a shared drive rack, DC-bus energy can be distributed from the central supply section to the controller that serves each motor.
The control section exchanges setpoint and diagnostic data through the SERCOS fiber-optic bus, allowing synchronous communication with the higher-level PLC and other connected drives. A continuous output capacity of 100 A is supported by busbars that route DC supply energy to the power stage. Heat produced by the switching devices is removed by a built-in air blower, so the unit uses self-contained airflow instead of external ducting. The fiber-optic link supports coordinated command updates, which is important when several axes must start, stop, or track position together. Compatibility with the DIAX04 family keeps the electrical and mechanical format aligned with other modules used in the same motion platform.
The product is Version 1. It is part of Line 03, which corresponds to this group's rated voltage range and connector layout. As a modular axis module, it handles one controlled motor channel within a shared rack and returns operating status to the central controller. This arrangement supports synchronized motion across multiple servo axes while keeping the power stage and control functions assigned to a specific axis. The version and line codes indicate the release grouping used for this model without changing its basic role as an HDS rack controller.
