Product Description
The Arkel ARCODE 4D75A is the premier choice for major lift projects requiring high power output, such as high-speed commercial lifts or heavy freight elevators. Belonging to the C/D Series, this unit is rated to handle robust elevator motors up to 37 kW and provides sufficient instantaneous power thanks to its 140 A maximum current capability.
The core strength of the ARCODE platform lies in its monolithic integrated design, where the VVVF drive (motor inverter), the control logic, and the emergency evacuation circuit all reside within a single synchronized housing. This holistic approach is crucial for high-speed operation, eliminating communication delays between the drive and the controller that plague multi-component systems.
Enhanced Performance and Scalability:
The 4D75A is engineered for the highest performance tier, supporting speeds up to 4 m/s and control over up to 64 stops. These advanced limits are typically unlocked by utilizing the HDA (Highline) Hardware Dongle. The system’s patented Direct Landing technology ensures that even at high speeds, stops are instantaneous and exceptionally smooth, dramatically reducing the overall journey time by eliminating the slow ‘creeping’ phase.
Its universal compatibility means the 4D75A can drive new-generation synchronous (gearless) motors using the ENCA card or older asynchronous (geared) motors using the ENCI card. This flexibility allows for large-scale phased modernization projects, where the control system can be installed immediately to gain superior efficiency and comfort, with the option to upgrade the motor later.
Frequently Asked Questions (FAQs)
Q1: What is the primary application environment for the ARCODE 4D75A?
Given its high nominal current rating of 75 A and its support for motors up to 37 kW (50 HP), the ARCODE 4D75A is ideally suited for high-rise commercial buildings, large hotels, and industrial applications. It is the most powerful unit in the 400V ARCODE series and is capable of managing complex traffic requirements, especially when configured with the Highline license for maximum speeds and group operations.
Q2: What is the difference between the Basic and Highline (HDA) licenses for the 4D75A?
The ARCODE platform uses licenses (or dongles) to unlock its full potential. The basic configuration is typically limited to 1.6 m/s speed and 16 floors. Since the 4D75A is designed for advanced projects, users will typically install the HDA (Highline) Hardware Dongle. This license removes the basic limits, allowing the unit to reach speeds up to 4 m/s, manage up to 64 stops, and control up to 8 lifts in a group.
Q3: How does the Direct Landing feature enhance a high-speed elevator like those controlled by the 4D75A?
In high-speed lifts, even a short stop time adds up significantly over many trips. Direct Landing technology eliminates the slow “creeping” phase used by traditional VVVF systems. The ARCODE 4D75A calculates the perfect deceleration curve dynamically using precise encoder data, ensuring that the car stops exactly at the floor level in a single, smooth, and rapid motion. This enhances passenger comfort and minimizes the total travel time, increasing traffic efficiency.
Q4: Which peripheral unit is mandatory for the installation and configuration of the ARCODE 4D75A?
The AREM handheld terminal is the mandatory peripheral unit required for system installation, adjustment, fault diagnosis, and software updates for all ARCODE devices. The ARCODE unit, like others in the lineup, relies on the AREM tool for performing essential commissioning processes such as Motor Auto-Tune and Digital Shaft Learning.
