Technical Specifications

Integrated Elevator Control Technology

The ARCODE platform is designed as a fully integrated elevator automation system. Instead of using separate inverter drives, control boards, and evacuation modules, the ARCODE 4B26A synchronizes all elevator control functions inside a single intelligent unit.

This integrated approach simplifies installation, reduces cabinet space requirements, lowers wiring complexity, and improves long-term maintenance reliability.

Advanced Direct Landing Performance

The Direct Landing technology used in the ARCODE platform allows the elevator to stop directly at floor level without entering traditional creep speed operation.

Using high-resolution encoder feedback, the system continuously calculates the dynamic travel curve and determines the optimal deceleration point in real time. This results in:

• Smoother passenger ride comfort
• More accurate floor leveling
• Reduced travel times
• Lower mechanical wear on elevator components
• Higher transportation efficiency

The technology is especially beneficial in medium-rise and high-traffic elevator applications where ride quality and operational efficiency are critical.

Suitable for Geared & Gearless Elevator Systems

The Arkel ARCODE 4B26A supports both synchronous gearless motors and asynchronous geared motors, making it highly flexible for different elevator modernization and new installation scenarios.

For modernization projects using existing geared machines, the system can operate with the ENCI incremental encoder card. When upgrading later to a gearless synchronous motor, the system can be adapted using the ENCA absolute encoder card.

This flexible structure allows building owners to modernize elevator control systems step-by-step while controlling investment costs.

Scalable ARCODE Platform Architecture

The ARCODE ecosystem uses scalable hardware licensing architecture. In its standard Basic configuration, the ARCODE 4B26A supports:

• Up to 1.6 m/s elevator speed
• 16 floors
• 2 elevators in group operation

With optional HDA licensing, the system can scale up to:

• 4 m/s elevator speed
• 64 floors
• 8 elevators in group control

This scalability makes the ARCODE platform suitable for both compact residential projects and larger commercial buildings.

Reliable CANbus Communication Infrastructure

The system uses robust CANbus serial communication between all elevator peripherals including COPs, LOPs, shaft devices, and additional control modules.

Compared to conventional parallel wiring systems, CANbus technology significantly reduces shaft wiring complexity while improving communication reliability and installation speed.

The result is a cleaner electrical installation, simplified troubleshooting, and improved long-term operational stability.
