HDS03.1-W100N-HA08-01-FW
The HDS03.1-W100N-HA08-01-FW is a modular drive controller produced by Bosch Rexroth Indramat for multi-axis automation. It converts motion commands into regulated motor current so torque and speed remain within programmed limits during servo operation. The unit occupies a single slot in the rack, which helps it fit compact assemblies used in packaging, material-handling, and machining centers. It supports closed-loop control for servo axes that must follow commanded motion with stable torque and velocity behavior. Front-mounted parameter modules allow the drive to be adjusted for different mechanical loads without changing the higher-level control program.
The controller exchanges setpoints and feedback through its analog command interface, allowing proportional voltage signals from motion cards to drive the internal current loops. As part of the DIAX04 family, the module works within a rack that uses shared power distribution and common bus couplers. Thermal management is handled by a built-in air blower, which moves cooling air across the heat sink fins during sustained operation. Under continuous duty, the power section can deliver a rated phase current of 100 A, which suits medium-frame servomotors that require strong acceleration and rapid reversals. The same rack platform also uses common diagnostic conventions across neighboring modules.
The unit is part of Line 03 in the series. It is also Version 1, which identifies the initial release of this controller variant. The module belongs to the HDS Drive Controllers series and is intended to operate with companion units in synchronized multi-axis stacks. In this format, companion modules can be arranged in the same rack for coordinated motion across several axes. The controller remains a rack-mounted module rather than a standalone drive.
