HDS03.1-W075N-HS93-01-FW
The HDS03.1-W075N-HS93-01-FW is a modular axis control module manufactured by Bosch Rexroth Indramat for the HDS Drive Controllers series. Designed for cabinet installation in multi-axis machining centers and automated assembly lines, it bridges high-level motion commands with the power electronics that energize individual servo motors. Its circuitry supervises current, velocity, and position feedback loops so commanded trajectories remain accurate under changing load conditions. This arrangement supports coordinated motion on machines that require stable axis timing and repeatable servo response during continuous operation.
This controller can deliver up to 75 A of regulated output, which sets the available current for the connected axis. Command data travel over the fiber-optic SERCOS ring, allowing synchronized position updates across the system within a millisecond cycle. Thermal stability is maintained by a built-in air blower, so cooling air moves through the housing without a separate external fan assembly. The module is based on the DIAX04 platform, which allows installation in shared backplanes that use common power sections, feedback connections, and safety links. This layout supports compact control cabinets where several axes operate from the same drive structure.
The product is part of Line 03, indicating the third design line in this controller platform. Its command interface remains consistent with the communication layout used by compatible systems, so the module can be added to fiber-optic drive networks without changing the basic control architecture. The cooling arrangement supports closed-cabinet operation by keeping internal temperatures within the expected operating range. The unit is Version 1 and is classified as an HDS Drive Controller. It is intended for applications that need a separate controller stage between the machine control and the motor power section.
