Product Description:

The HDS03.2-W075N-HS84-01-FW is a modular servo drive controller produced by Bosch Rexroth Indramat in the HDS Drive Controllers series. It occupies one slot in a DIAX04 drive stack and links to a shared DC bus to modulate the three-phase output supplied to attached motors. The controller acts as the power stage between the common bus and the motor, converting incoming electrical energy into regulated motion output. In automated machining cells, packaging lines, and gantry systems, it translates high-level motion commands into timed current and voltage patterns that govern axis speed, torque, and position.

Inside the stack, the controller exchanges data over the optical SERCOS ring, so command telegrams, feedback, and drive status remain synchronized with low latency across coordinated axes. Thermal regulation relies on a built-in air blower, which directs cabinet air across the heat sink without additional ductwork and helps remove heat from the power section during sustained operation. The power electronics are rated for 75 A continuous output, giving the unit the current capacity needed for rapid acceleration of medium-inertia servomotors. Compatibility with the DIAX04 motion platform allows the controller to operate alongside matching supply and axis modules in the same drive stack.

The unit is part of Line 03, which places it within the third design line of this controller platform. Its control section is Version 2, providing a clear revision level for this hardware format. Documented as an HDS Drive Controller, the module bolts to adjacent supply and auxiliary units, which shortens DC bus links and signal wiring inside the cabinet. This layout supports compact multi-axis installations where several controllers must be mounted side by side with consistent electrical spacing and organized internal routing.
