FST-861 Elevator Integrated Controller 5.5-45KW

The FST-861 Elevator VFD Drive is an integrated controller and vector inverter that combines elevator control logic and variable frequency drive technology in a single compact unit. Featuring a parallel communication architecture, the FST-861 delivers direct point-to-point signal wiring for maximum reliability and easy troubleshooting — the preferred choice for high-rise applications above 32 floors.

• Integrated control and drive in a compact structure with simple operation
• Parallel communication architecture: direct point-to-point wiring for every signal point, fast response, strong anti-interference capability, and easy on-site troubleshooting
• Ideal for high-rise buildings above 32 floors — handles large I/O counts with clear, reliable point-to-point signal transmission
• Strong environmental adaptability, achieving self-learning of weighing at any weight
• Multiple security protections, in accordance with GB/T7588.1/2020 standard
• Dual chip control for operation and holding brake function
• High-performance vector control — economical and easy to use, improving safety and stability
• Flexible wiring compatibility — suitable for both new installations and retrofit projects using traditional parallel wiring
• Flexible and rich modular value-added accessories

The FST-861 adopts a parallel communication architecture with direct point-to-point signal wiring, while the FST-860 adopts a serial bus communication architecture. Compared to the FST-820 (dedicated closed-loop vector) and FST-880 (open-loop vector), both the FST-860 and FST-861 are all-in-one integrated solutions combining control and drive in one unit — eliminating the need for a separate PLC and VFD — differing mainly in communication architecture.

Fully compliant with GB/T7588.1-2020 (elevator safety standards) with built-in overspeed protection, safety self-test, and forced speed change detection to prevent top/bottom impacts.

The integrated design reduces panel space by 40%, simplifies wiring, and lowers installation costs. Dual chip control ensures redundant safety for brake control and operation logic. With the parallel architecture, every input/output point corresponds to a dedicated terminal, so maintenance personnel can locate faults directly at the terminal level without bus diagnostics.
