Functions and Features of Fuji Elevator Controller

When sourcing for Fuji elevator controllers and other elevator components, it's essential to understand their operational principles and advanced capabilities. The Fuji elevator controller is a sophisticated control system designed to ensure safe, efficient, and intelligent vertical transportation in residential, commercial, and industrial buildings. Below is a detailed breakdown of its core functions and key features that make it a reliable choice in modern elevator systems.

Core Functions of the Fuji Elevator Controller

The controller acts as the central nervous system of the elevator, coordinating all mechanical and electrical operations. It processes input signals from call buttons, safety sensors, floor detectors, and load measurement devices to manage door operation, motor control, speed regulation, and emergency responses. Its primary goal is to deliver smooth, timely, and secure elevator performance while minimizing energy consumption and maintenance needs.

Microprocessor Control

The Fuji elevator controller is built around advanced microprocessor technology, which serves as the brain of the system. This high-speed processor continuously monitors and manages various inputs and outputs, including floor requests, door status, motor feedback, and safety interlocks.

It enables real-time decision-making for optimal dispatching, ensuring that elevator movements are coordinated efficiently. By integrating logic-based algorithms, the microprocessor enhances system responsiveness, reduces downtime, and supports seamless integration with building management systems (BMS) for centralized monitoring and diagnostics.

Smart Landing Technology

Smart Landing is a signature feature of the Fuji controller that significantly improves passenger experience and operational efficiency. Using dynamic traffic analysis and predictive algorithms, the system determines the most logical stopping pattern based on current call patterns, direction of travel, and floor demand.

This intelligent dispatching reduces unnecessary stops, shortens waiting times, and optimizes round-trip cycles—especially during peak hours. For example, in high-rise buildings, Smart Landing can prioritize express service to major transfer floors, improving throughput and reducing congestion.

Variable Voltage and Frequency Drive (VVVF)

The VVVF drive system is integrated into the Fuji controller to enable precise control over the elevator motor’s speed and torque. By adjusting both voltage and frequency supplied to the motor, the system ensures smooth acceleration and deceleration, eliminating jerky movements and enhancing ride comfort.

VVVF technology also contributes to energy savings by reducing power consumption during startup and low-load conditions. Compared to traditional resistance-based drives, VVVF systems are quieter, more reliable, and have a longer service life, making them ideal for modern energy-efficient buildings.

Load Weighing Device (LWD)

The Load Weighing Device is a critical safety and performance feature embedded in the Fuji controller. Installed beneath the elevator car, the LWD uses strain gauges or pressure sensors to accurately measure the total weight of passengers and cargo in real time.

Based on this data, the controller dynamically adjusts motor torque, acceleration, and braking force to maintain consistent performance regardless of load. If the rated capacity is exceeded, the system triggers an audible and visual overload alarm and prevents the doors from closing until the excess weight is removed—ensuring compliance with safety standards and preventing mechanical stress.

Self-Diagnostic Function

To maximize uptime and reduce maintenance costs, the Fuji elevator controller includes a comprehensive self-diagnostic system. This function continuously monitors the health of all connected subsystems, including motors, brakes, door operators, safety circuits, and communication lines.

When an anomaly is detected—such as a misaligned door sensor, irregular current draw, or communication error—the controller logs the fault code and can alert maintenance personnel via remote monitoring systems. Early detection allows for proactive repairs, minimizing unexpected breakdowns and extending equipment lifespan.

Energy Efficiency & System Integration

Beyond core functionality, the Fuji controller supports eco-friendly operation through regenerative drive compatibility and standby power reduction modes. During descent with load or ascent with light load, regenerative drives can feed excess energy back into the building grid, reducing overall energy consumption by up to 30%.

The controller also supports integration with IoT platforms, fire alarm systems, security access controls, and destination dispatch systems, enabling smart building automation and improved user convenience through mobile apps or card-based access.

Fuji Elevator Controller: Frequently Asked Questions

Q1: What is the main function of an elevator controller?

The elevator controller acts as the central "brain" of the elevator system, responsible for managing all aspects of elevator operation. Its primary function is to determine the elevator car's current position and direct the movement mechanism—whether it's a hydraulic pump or traction motor with cables—to transport the car safely and efficiently to the requested floor.

Beyond basic movement, modern controllers coordinate door operations, respond to call buttons (inside and outside the car), manage traffic flow during peak times, and interface with building management systems. They ensure smooth acceleration and deceleration, precise floor alignment, and optimal energy usage throughout the journey.

Q2: What is a PCB controller for elevators?

A PCB (Printed Circuit Board) elevator controller is an advanced control system that uses a custom-designed circuit board to house and connect all essential electronic components. Unlike older electromechanical systems, PCB controllers rely on integrated circuits, microcontrollers, and solid-state components mounted on a laminated board with conductive pathways.

These controllers are widely adopted in modern elevator systems due to their superior stability, compact design, and high reliability. The use of a PCB minimizes wiring complexity, reduces the risk of loose connections, and enhances resistance to electrical noise and vibration—critical factors in ensuring consistent elevator performance and safety over time.

Q3: How does a Fuji elevator controller work?

The Fuji elevator controller operates using a sophisticated microprocessor-based system that continuously monitors and manages every phase of elevator operation. It receives real-time input signals from various sources, including floor call buttons, cabin controls, door sensors, position encoders, safety switches, and load detectors.

Based on this data, the controller processes the information using embedded software algorithms to determine the most efficient route and sequence for responding to calls. It then sends precise commands to key components such as the drive motor, brake system, door operators, and indicator lights.

Critical to its function is the built-in safety monitoring system. The controller constantly checks parameters like speed, position, door closure, and emergency signals. If any anomaly is detected—such as overspeed, misleveling, or obstruction—it immediately initiates corrective actions, including stopping the elevator and alerting maintenance systems to prevent accidents.

Q4: What are the advantages of a microprocessor-based controller?

Microprocessor-based controllers, like those used in Fuji elevator systems, offer significant technological and operational advantages over traditional relay-based systems:

• High Precision & Reliability: Digital processing ensures accurate floor leveling and consistent response times, reducing mechanical wear and passenger discomfort.
• Energy Efficiency: Advanced control algorithms optimize motor usage, reducing power consumption during acceleration, cruising, and idle states.
• Complex Task Management: Capable of handling multitasking operations such as managing multiple cars in a group, prioritizing emergency calls, and adapting to traffic patterns throughout the day.
• Diagnostic Capabilities: Built-in self-diagnostics and error logging allow for predictive maintenance and faster troubleshooting, minimizing downtime.
• Software Upgradability: Firmware can be updated to enhance performance, add features, or improve safety protocols without replacing hardware.
• Integration Flexibility: Easily interfaces with building automation systems, access control, fire alarm systems, and remote monitoring platforms.
