High-Speed Elevator Control System with 3–10 m/s Speed Range, EN81 Safety Standard, and Four-Quadrant Drive

Speed range: 3–10 m/s
Floor height ≤ 64 floors
Suitable for full-selection elevators, parallel elevators, conventional group-control elevators, and destination-based group-control elevators (supporting up to 8 units).

Redundant and reliable design, dual-CPU board control, and an independent speed monitoring board.
Contactless terminal deceleration switch, featuring Gray code encoding for input, which reduces the number of switch input points and enhances the reliability of switch operation.
A complete electrical stability assurance solution featuring stroke-reducing buffers certified by a national authoritative testing agency.

Adopt a four-quadrant variable-frequency control drive system.
AFE Active Front End: It can effectively control the bus voltage, enable efficient energy feedback, and ensure that the harmonic content of the feedback current is ≤5%.
The variable-frequency drive employs torque feedforward technology to enhance the responsiveness of speed control. Even under high acceleration (or deceleration) conditions, it delivers outstanding speed-tracking performance, ensuring elevator stability.

Data is transmitted between the control system and the drive system via CAN-BUS communication, enhancing the precision and reliability of speed control.

Modular cabinet design with flexible configuration, adaptable to elevators with varying speeds and load capacities.
Excellent thermal design enhances system reliability.
The power cables inside the cabinet are routed using copper busbars, ensuring clear wiring and high reliability.
