Product Description

The Arkel ARCODE 4B10A is a pioneering Integrated Lift Control Unit (ILCU), featuring a 400V input and 10A nominal output current. Arkel developed ARCODE to revolutionize the lift sector by integrating the VVVF drive (inverter), control board (controller), and emergency evacuation system into one synchronized, compact structure. This centralized architecture ensures that the control logic and motor drive function in perfect harmony, guaranteeing a seamless and precise travel experience.

Where It’s Used (Kullanım Alanları):

The compact nature of the ARCODE 4B10A makes it highly advantageous for environments with limited space, particularly Machine-Room-Less (MRL) applications. Its universal compatibility with both synchronous (gearless) and asynchronous (geared) motors makes the 4B10A an excellent choice for new installations requiring a cost-effective 10A solution. It is particularly effective for modernization projects as it allows the upgrading of the control system (using the ENCI card for existing asynchronous motors) before the eventual motor replacement (using the ENCA card for new synchronous motors).

Key Functionality and Performance:

The ARCODE system is centered around Direct Landing technology, which calculates the travel curve dynamically and eliminates the low-speed “creeping” phase typical of older VVVF systems. This dramatically reduces travel time and enhances passenger comfort.

As a foundational model, the 4B10A is typically classified under the BASIC ARCODE license (which can be upgraded via hardware dongles like MDA/HDA for greater performance), enabling essential functionality such as operation up to 1.6 m/s and managing up to 16 floors (or 2 lifts in a group). The system includes robust features designed by Arkel, an R&D leader in the industry since 1998, such as:

• Auto-Tuning and Shaft Learning: Automated digital configuration processes that minimize the need for manual, on-site parameter input.
• Modular Ecosystem: Uses CANbus communication to simplify shaft wiring and ensure easy expansion and integration with Arkel peripherals like AREM (Handheld Terminal) and ARLIFT (Internet Cloud Connection Unit).
• Emergency Operation: Equipped with an integrated rescue system that can operate via a 60-120VDC battery supply or 220VAC UPS to safely bring the car to the nearest or specified floor during power outages.

Frequently Asked Questions (Sık Sorulan Sorular) and Answers

Q1: What are the main limitations of the ARCODE 4B10A compared to higher-rated models (e.g., 4C50A)?

The 4B10A model is rated for a Nominal Output Current of 10A. Its main limitations are related to power capacity (current handling) and default software features. Out of the box, it supports lower speeds (up to 1.6 m/s) and fewer stops (up to 16 floors), fitting smaller, less demanding applications (Basic License). Higher-rated models like the 4C50A (50A nominal current) are designed for higher capacities, allowing for faster speeds (up to 4 m/s) and more stops (up to 64 floors) when equipped with the Highline dongle.

Q2: Does the ARCODE 4B10A require an absolute encoder for synchronous motors?

For Synchronous (Gearless) motors, the ARCODE system generally uses the ENCA (Encoder Absolute) card to interface with high-resolution absolute encoders (such as EnDat, SSI, SinCos, or BISS). The absolute encoder is required for the system to perform essential functions like Static Auto-Tuning (without lifting ropes). However, for Asynchronous (Geared) motors, the less complex ENCI (Incremental Encoder Card) is used.

Q3: Can the ARCODE 4B10A be used in elevator modernization projects?

Yes, the ARCODE 4B10A is well-suited for modernization projects. Its universal motor compatibility means it can drive existing asynchronous motors (using the ENCI card). This allows clients to upgrade the outdated control panel first, immediately gaining benefits like Direct Landing and improved safety, and postponing the more expensive motor replacement to a later phase.

Q4: How is emergency rescue operation handled if the building loses power?

The ARCODE has an integrated evacuation system. In case of a main power failure, the unit automatically switches to a backup power source (either a 60-120VDC battery bank or a 220VAC single-phase UPS connected to the L1 and L3 terminals). The system then drives the car to the nearest or a preset emergency floor to safely evacuate passengers. This rescue function is only supported for closed-loop operation.
