Intelligent Control Leads the Future

GKL is the new generation intelligent elevator integrated controller. It perfectly combines the functions of logical control and variable frequency drive. It has Advanced Technology, Optimal Performance, High Reliability, Easy to Use and many more properties.


1. Advanced Technology

◎ Perfectly combine intellectual logic control and high performance VVVF drive control to achieve completely integration.

◎ Advanced vector control technology, demodulates motor with high precision, takes full advantage of motor capacity, improves elevator performance and riding comfort.

◎ Adopts advanced space vector PWM control method, improves great efficiency than traditional sine/cosine PWM method and saves more energy.


2. Optimal Performance

◎ Generates optimized speed curve based on target floor to make lift direct-stop with high precision and efficiency.

◎ CAN BUS technology satisfies serial communication in high speed and reliability. Simplifies system for wiring and extension.

◎ Adopts wireless/LAN remote control interface, convenient for long distance control, maintenance and elevator monitoring.


3. Easy to Use

◎ Supports two types auto-tuning (self-learn) methods, Rotating and Static, to compute motor parameters and initial angle.

◎ Fuzzy logic control with non-load-compensator for easy lift start-up. Excellent comfort feeling even without lift weighting device.

◎ When working with Bluelight Synchronous traction machine, controller can pre-define the machine type and automatically save the data. Spares the process of machine parameter inputting and auto-tuning, improves the tuning efficiency and maximize machine performance.


4. High Reliability

◎ Advanced double 32bit CPU and FPGA for complete elevator control to ensure high elevator safety and reliability.

◎ Redundancy design and full software-hardware protection to guarantee elevator safety and reliability.

◎ Professional EMC tested, fully enhance anti-electromagnetic interference ability and suitable for complicated job site.

◎ Monitoring the cutting current from controller to main motor every time when elevator stops.
