- Strong environmental adaptability, achieving self-learning of weighing at any weight
- Multiple security protection, in accordance with GB/T7588.1/2020 standard
- Dual chip control operation and holding brake function
- High performance vector control, economical and easy to use, improves safety and stability
- Perfect combination of CANbus and Modbus communication
- Flexible and rich modular value-added accessories
Differences from FST-820/FST-880: Compared to the FST-820 (dedicated closed-loop vector) and FST-880 (open-loop vector), the FST-860 is an all-in-one integrated solution combining control and drive in one unit, eliminating the need for separate PLC and VFD.
Compliance with the new national standard: 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.
Detailed explanation of integration advantages: 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.
