HDS03.1-W100N-HA25-01-FW
The HDS03.1-W100N-HA25-01-FW is a three-axis drive controller produced by Bosch Rexroth Indramat for the HDS Drive Controllers series. It forms part of a modular motion package that supplies regulated DC power to servo drives and processes feedback from position loops, making it a central actuator interface in automated machining cells, material-handling lines, and palletizers. The unit converts control demands into regulated drive output so connected axes can respond with stable torque and speed behavior during coordinated motion. Because it sits between the control system and the motor power stage, it supports closed-loop axis control where repeatable motion and consistent response are important.
Command signals reach the unit through an ANALOG interface, allowing direct velocity or torque references from legacy PLC cards without extra fieldbus hardware. Thermal management is handled by a built-in air blower that moves cabinet air across the heat sink, so standard enclosures do not require external ducting for routine cooling. The power stage supports a continuous motor supply of 100 A, giving the controller enough current for demanding acceleration profiles on multiple axes that share a common DC bus. The internal airflow path helps keep the heat sink effective during continuous operation in standard industrial cabinets. This arrangement supports multi-axis layouts where stable current delivery and steady heat removal are needed over repeated machine cycles.
The controller belongs to the DIAX04 family, which is used for synchronized motion in modular drive systems. Within that family, it is part of Line 03. The unit is Version 1 and supports position-control loops with ±10 V references. It also includes diagnostic trace memory for observing operating behavior and following signal changes during operation. Its control features fit servo axes that need precise following performance and clear diagnostic visibility.
