Product Description:

The HDS03.2-W100N-HA09-01-FW drive controller is produced by Bosch Rexroth Indramat and belongs to the HDS Drive Controllers series within the DIAX04 automation platform. It is a modular inverter section intended to regulate servo axes, delivering shaped current and voltage for high-response motors used on presses, packaging lines, and material-handling gantries. Installed in a power rack, the unit converts DC bus power into controlled three-phase outputs and relays torque commands from the motion program to each motor channel. Its modular format allows it to operate alongside shared supply components and other drive sections in the same rack.

The device exchanges setpoint and feedback signals through an analog command interface, permitting direct connection to PLC cards that output ±10 V references. Its power stage is rated for a continuous motor current of 100 A, so the downstream axis can draw high torque without saturating the IGBTs. Thermal management is handled by a built-in air blower that forces cabinet air across the heat sink and keeps semiconductor temperatures within the permitted range. This arrangement supports stable operation during demanding servo motion, especially where rapid load changes occur. The controller is intended for applications that use analog command signals rather than network-based motion input.

This controller is part of Line 03 and is built as Version 2. Those identifiers indicate the connector orientation, the diagnostic LED layout, and the compatible control generation used with this unit. Within the wider HDS architecture, it serves as the higher-current slot so mixed racks can combine smaller auxiliary axes with a main axis controller in one assembly. That layout supports multi-axis systems that need different drive capacities without changing the basic rack structure.
