Technical Specifications

Integrated Elevator Control Architecture

The ARCODE platform eliminates the need for separate inverter, controller, and evacuation modules by integrating all critical elevator control functions into a single synchronized system. This approach significantly reduces installation complexity while improving communication reliability between system components.

Compared to conventional multi-board elevator systems, the ARCODE 4C35A simplifies commissioning, reduces wiring requirements, and minimizes troubleshooting time during maintenance operations.

Direct Landing Technology

One of the most advanced features of the ARCODE platform is its patented Direct Landing technology. Traditional elevator systems typically slow down into creep speed before reaching the floor, causing longer travel times and less comfortable stops.

ARCODE continuously calculates the car position using high-precision encoder feedback and dynamically determines the optimal deceleration curve. This allows the elevator to stop directly at floor level in one smooth motion without entering creep speed.

The result is:

• Smoother passenger comfort
• Improved leveling precision
• Reduced travel times
• Lower mechanical wear
• Higher transportation efficiency

Designed for Modernization & MRL Projects

The compact enclosure and integrated design make the Arkel ARCODE 4C35A especially suitable for Machine-Room-Less (MRL) elevator applications where panel space is limited.

It is also highly advantageous for elevator modernization projects. Existing geared machines can initially operate with the ENCI incremental encoder card, allowing building owners to modernize the control system without immediately replacing the traction machine.

Later, when upgrading to a synchronous gearless motor, the system can be adapted simply by switching to the ENCA absolute encoder card.

Scalable Elevator Performance

The ARCODE ecosystem is designed with scalable licensing architecture. In its standard Basic configuration, the system supports:

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

With optional MDA or HDA hardware dongles, the platform can scale up to:

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

This flexibility allows elevator companies to standardize hardware across different project sizes while expanding system capability through licensing.

Advanced CANbus Communication

The ARCODE system uses robust CANbus serial communication between peripherals, hall stations, car operating panels, and shaft devices. This architecture simplifies shaft wiring, reduces installation errors, and improves long-term communication reliability.

The result is faster installation, easier maintenance, and improved system stability in high-traffic elevator environments.
