The following table details the specifications found for the ARCODE 4B17A:

Product Description (Body Content)

The Arkel ARCODE 4B17A stands out as a highly efficient and industrialized lift control unit, certified for three-phase 400V systems. Its primary strength lies in its ability to centralize three crucial elevator functions—the VVVF frequency inverter, the main controller logic, and the emergency evacuation system—into one housing,. This complete integration eliminates complex inter-component communication issues, ensuring full synchronization between the controller and the motor drive for flawless operation,.

Core Technology and Comfort:

ARCODE’s design is heavily influenced by enhancing passenger experience, primarily through its patented “Direct Landing” technology. This intelligent feature constantly monitors the car’s position via the motor encoder and dynamically calculates the ideal deceleration path for every single trip,. By eliminating the low-speed “creeping” phase common in older systems, Direct Landing provides smooth, accurate stops and measurably reduces total travel time, thereby improving traffic efficiency in the building.

Application in Modern and Existing Systems:

The 4B17A, with its 17A nominal rating, is commonly specified for elevators in mid-rise residential or small commercial buildings utilizing motors up to 7.5 kW,. This unit is particularly attractive for Machine-Room-Less (MRL) installations due to its compact physical design, which saves valuable space in the shaft,.

For modernization projects, the ARCODE platform offers unparalleled flexibility. It can drive both modern synchronous motors (using the ENCA card for absolute encoders) and existing asynchronous motors (using the ENCI card for incremental encoders). This ability supports a phased modernization strategy, allowing system operators to immediately improve travel comfort and efficiency by upgrading the control unit first, without necessitating a costly motor replacement upfront.

The system’s installation is expedited by using the dedicated AREM handheld terminal, which manages all configuration, fault diagnostics, and software updates for all connected peripherals via the robust CANbus communication network,.

Frequently Asked Questions (FAQs)

Q1: What are the primary performance limitations of the ARCODE 4B17A in its standard configuration?

The ARCODE 4B17A operates under the Basic License when installed without any optional hardware dongles (MDA or HDA),. In this configuration, the unit is suited for typical applications, limiting the maximum operational speed to 1.6 m/s and supporting up to 16 floors in single or duplex operation (max 2 lifts),.

Q2: What motor power output is the 4B17A specifically designed to handle?

The ARCODE 4B17A has a nominal current rating of 17 A and is generally designed to operate lift motors with a maximum power of 7.5 kW (10 HP),. The unit can handle instantaneous starting currents up to 34 A for short periods (less than 6 seconds),.

Q3: How does ARCODE’s design aid elevator modernization projects?

ARCODE is highly beneficial for modernization as it is compatible with both new synchronous and older asynchronous motors. This flexibility is managed through plug-in encoder cards (ENCI for existing asynchronous motors and ENCA for new synchronous motors). This capability allows lift owners to implement a cost-effective, phased upgrade, replacing the control system first to immediately introduce features like Direct Landing and enhanced safety, before scheduling a future motor replacement.

Q4: Can the ARCODE 4B17A’s capacity be increased beyond 1.6 m/s and 16 floors?

Yes, the ARCODE platform is designed for scalability. While the 4B17A comes with Basic license limitations, its performance can be upgraded by purchasing and installing hardware license dongles,. For example, the MDA dongle can expand limits up to 2.5 m/s and 24 floors, while the HDA dongle can enable high-rise applications up to 4 m/s and 64 floors,.
