HDS03.1-W100N-HA42-01-FW
The HDS03.1-W100N-HA42-01-FW is a drive controller produced by Bosch Rexroth Indramat for the HDS Drive Controllers series. Within a multi-axis system, it supplies regulated DC power and axis control signals to servo drives, allowing coordinated motion in machining centers, packaging lines, and assembly stations. It bridges the higher-level automation system and the individual servo modules by processing reference commands and maintaining motor current loops for accurate velocity and position control. This role lets the rack manage synchronized axis behavior during acceleration, deceleration, and holding phases without requiring separate control hardware for each motor channel.
This unit exchanges setpoints and feedback through an analog command interface, which allows legacy PLC hardware to send continuous ±10 V signals without protocol conversion. It belongs to the DIAX04 family, so its mechanical size and connectors match other modules in that platform. Thermal management is handled by a built-in air blower that pulls cabinet air across the heat sink without external ducting. The power section is rated for 100 A of continuous output, which is suitable for multiple medium-frame servo drives on a common DC bus. In systems that keep older analog controls in service, this arrangement preserves direct command response and avoids unnecessary interface layers.
The unit is part of Line 03 and is released as Version 1. It is an HDS Drive Controller that works with compatible motion cards on the same backplane and supports consistent status handling across the platform. The housing layout and operating scheme remain aligned with the rest of the product line, so module placement and signal routing stay straightforward in multi-axis assemblies. Its backplane integration also helps centralize power distribution and control exchange within the rack, keeping the axis package compact and organized.
