Product Description:
The HDS03.2-W100N-HA08-01-FW belongs to the HDS Drive Controllers series. As a drive controller, it forms the power and control link between a DIAX04 servo drive system and the connected motor, supplying regulated current for closed-loop operation and responding to motion commands from the machine control. The module is intended for coordinated servo applications that depend on stable current regulation and fast response to changing loads. It is used in automated machining cells, material-handling lines, and packaging equipment where precise axis behavior is required.
This model uses an analog command communication interface, so the axis card or PLC must provide differential voltage or current signals instead of fieldbus messages. This arrangement fits systems that generate command values directly in analog form and pass feedback values through the same style of control structure. It sits inside the DIAX04 rack, where the controller shares a common backplane with matching auxiliary modules and bus rails. Thermal loading is removed by a built-in internal air blower that draws cabinet air across the heat sinks, so no external heat exchanger is required. The controller is rated for a continuous output of 100 A, giving it the current capacity needed for medium-to-large synchronous or induction motors during acceleration. The product is part of Line 03 in the series, so connector layout and diagnostic indicators follow the same design generation as other 03-line units.
Within the HDS Drive Controllers platform, the unit operates as a coordinated axis module for precise torque, velocity, and position loops. Produced by Bosch Rexroth Indramat, it supports Indramat motor feedback formats and emergency-stop circuits used across that automation platform. Classified as an HDS Drive Controller, the device does not contain embedded motion programs, so control logic remains in the master NC or PLC instead of inside the drive. The product is Version 2, which adds higher-resolution current measurement and improved fault logging during operation.
