HDS03.1-W100N-HA44-01-FW
The HDS03.1-W100N-HA44-01-FW is a drive controller manufactured by Bosch Rexroth Indramat for the HDS Drive Controllers series. In automated machining cells and material-handling stations, it regulates servo power modules so connected axes can accelerate, decelerate, and hold position under closed-loop control. The unit works with motion processors in the DIAX04 family and supports coordinated multi-axis movement over a shared DC bus. This arrangement helps keep cabinet layouts compact while allowing several drive sections to operate together in one motion system. It is intended for multi-axis installations where a compact power and control structure is important.
The command channel uses an analog interface, so the controller can accept continuous voltage references for speed or torque commands without digital step effects. Thermal management is handled by a built-in air blower that moves cabinet air across the heat sink, avoiding the need for external ductwork and helping stabilize internal temperatures during sustained operation. The inverter stage is rated for 100 A of continuous output current, which makes the unit suitable for high-torque motors and other demanding axis applications. This model is part of Line 03, placing it within the third design line of the HDS platform.
The controller is Version 1. This release corresponds to the first production version for the model and is compatible with early master controllers used in coordinated drive systems. In a centralized drive cabinet, it provides controlled motor power for axes that must respond smoothly to changing commands during positioning, speed regulation, and load holding. Because it is used in synchronized multi-axis systems, the unit suits machine sections where several motions must start, stop, and change speed in relation to one another without unpredictable response.
