HDS03.1-W100N-HA14-01-FW
The HDS03.1-W100N-HA14-01-FW drive controller is produced by Bosch Rexroth Indramat in the HDS Drive Controllers series. It serves as the regulated power and command stage in multi-axis systems, converting control inputs into precise motor current for coordinated servo motion. In packaging lines, pick-and-place gantries, and printing presses, the unit connects supply modules, feedback devices, and motors so axes can accelerate, decelerate, and hold position in step with the machine process. It also helps the higher-level control maintain smooth transitions between motion segments by delivering regulated current to the connected servo motor. This arrangement supports synchronized movement where several axes must respond quickly and maintain stable positioning during repeated cycles.
The unit uses an ANALOG command interface and responds to standardized voltage references for speed or torque control instead of digital fieldbus communication. It is part of the DIAX04 platform, so it matches companion modules used in the same drive system and fits the shared mechanical layout of that platform. Thermal management is provided by a built-in air blower, which moves enclosure air across the heat sinks and supports cabinet installation without external ducting. The internal airflow helps remove heat from the power section during continuous operation and rapid load changes. Because commands are electrical analog signals, response depends on stable reference inputs from the surrounding control hardware.
The product is part of Line 03, which places it in the mid-range power stage format used for this controller family. Its power circuitry can supply 100 A of continuous output current, which suits axes that require sustained torque during repeated starts, stops, and speed changes. The continuous current rating supports operation in applications where acceleration and holding duties occur in frequent sequence. The controller is released as Version 1, identifying the design revision used for this model. This revision is used for the configuration described here and keeps the controller aligned with the intended module grouping.
