HDS03.2-W100N-HA12-01-FW
The HDS03.2-W100N-HA12-01-FW is a drive controller manufactured by Bosch Rexroth Indramat and supplied in the HDS Drive Controllers series. Installed on a common DC bus with compatible power modules, it forms the command and regulation layer that translates higher-level motion commands into axis-specific current profiles. In automated machining centers, packaging lines, and material-handling cells, the unit coordinates torque and velocity loops so several axes can be managed from a single rack. It is used as the regulation section of a modular drive system, separating axis control functions from the shared supply hardware.
The controller exchanges setpoint commands and feedback through an analog command interface, so speed or torque references can be applied as ±10 V signals from a PLC or motion card. This interface suits systems that provide reference commands in conventional analog form. Thermal management is handled by a built-in air blower, which moves cabinet air across the heat-sink fins and removes the need for external ducting. As part of the DIAX04 platform, the device shares a common backplane bus and diagnostic structure with related modules. Its power stage is rated for 100 A of continuous motor current, giving it enough current capacity for high-inertia servo axes and similar demanding loads.
The unit is part of Line 03, which identifies its design line within the product range. The controller is Version 2, so it should be matched with the correct parameter set for that release. Its placement in the rack is at the regulation level rather than the power-supply level. That role places the unit between the higher-level controller and the motor power section during multi-axis operation. In the rack, it handles command processing and current regulation rather than incoming power conversion.
