HDS03.1-W100N-HA26-01-FW
The HDS03.1-W100N-HA26-01-FW is a modular drive controller produced by Bosch Rexroth Indramat and positioned within the HDS Drive Controllers series. Designed for multi-axis servo applications, the device functions as the power interface between a supply module and synchronous or asynchronous motors. It translates velocity or torque commands from the machine control layer into regulated armature currents. This operating role supports closed-loop motion control while helping keep cabinet layouts compact in metal-cutting, packaging, and handling equipment. Its modular format also fits drive systems that separate supply, control, and power functions across matched units.
The controller has a continuous output rating of 100 A, allowing it to drive high-torque axes without external amplifiers. Command values enter through an analog interface, so standard ±10 V references from PLCs or positioning cards can modulate speed or torque in real time. That input method works well with many existing motion-control sources that use analog command signals. Thermal management is provided by a built-in air blower that circulates cabinet air across the heat sink, eliminating the need for separate ducted cooling. The unit is part of the DIAX04 family, giving it mechanical and bus compatibility with matching supply and interface modules. It is also part of Line 03, which corresponds to this current class and connector arrangement.
The drive is Version 1, which is the initial release for this model. It is classified as an HDS Drive Controller, so it receives power from separate supply units rather than containing rectifiers on board. The power conversion stage therefore remains in the supply module instead of inside the controller housing. This layout keeps the controller centered on current regulation and coordinated operation within the larger drive system. It can therefore be used in modular installations where the supply section is installed as a separate system module.
