Product Description:

The HDS03.2-W100N-HS92-01-FW is a drive controller produced by Bosch Rexroth Indramat and supplied within the HDS Drive Controllers series. In multi-axis automation, the unit functions as the power and control stage that links a supply module to servo motors and executes real-time torque and speed commands for coordinated machine motion. By regulating motor current and feedback in a closed loop, it supports precise position control in packaging lines, machine tools, and material-handling cells where repeatable axis response is required during acceleration, dwell, and positioning.

The control loop exchanges process data through the SERCOS fiber-optic bus, so synchronous setpoint updates can occur without electrical noise. This communication method keeps cyclic data exchange synchronized across multiple axes and reduces sensitivity to electrical interference from nearby power wiring. A continuous drive output of 100 A is available, enabling the axis amplifier to energize medium-to-large permanent-magnet servomotors during heavy acceleration or sustained load changes. Heat generated by the IGBT bridge is removed by a built-in air blower, which circulates cabinet air across the heat sink instead of relying on a separate external fan assembly. The controller is part of the DIAX04 family, so it can be used in multi-axis drive systems with matching modules. The product is part of Line 03, which indicates the third design line used for this model.

The unit is Version 2. It handles command processing inside the DSP, so the host controller only forwards vectors over the high-speed interface while the drive closes the fast internal control loops locally. This arrangement keeps time-critical regulation inside the drive and reduces the amount of motion-related traffic handled at the supervisory level. The fan maintains directed airflow, allowing nearby drives to be stacked without external ducting and helping cabinet layouts remain compact when several axes are installed side by side.
