This model, specifically rated for 5.5 kW power and 14 A nominal current at 400V, is a versatile and popular choice within the advanced ADrive series, offered by ISF Elevator Shop. It delivers sophisticated vector control, essential safety features, and significant energy savings for a wide range of residential and light commercial elevator applications.

Key Features & Benefits (ADrive 4B055):

• Optimized for 5.5kW Motors: Ideally suited for controlling elevator motors up to 5.5 kW (~7.5 HP), providing efficient power management.
• Superior Ride Comfort: Ensures exceptionally smooth starts, stops, and travel through precise VVVF vector control, minimizing vibrations and operational noise. Features the crucial Anti-Rollback function for seamless operation.
• Energy Efficiency: Significantly reduces electricity consumption compared to traditional drive systems, contributing to lower building operating costs and environmental impact.
• Precise Speed & Position Control: Maintains accurate speed profiles and ensures precise floor leveling, independent of load conditions.
• Dual Motor Compatibility: Compatible with both standard Asynchronous (Induction) motors (open or closed loop) and modern Synchronous (Gearless) motors (closed loop, requires optional ENCABIT-Plus for absolute encoders).
• Emergency Evacuation Ready: Supports reliable emergency operation during power failures using external 24VDC control power and an appropriate battery pack (60-120V) or UPS system.
• Robust Protection Suite: Features integrated protection against overcurrent, over/undervoltage, short circuits, phase loss, drive/motor overheating (PTC input capable), and more. EMC test certified.
• User-Friendly Operation: Comes with an integrated LCD screen and 5-key keypad for easy parameter configuration, monitoring, and diagnostics using elevator-specific terminology.
• Advanced Functionality: Supports auto-tuning procedures, stores the last 256 faults for diagnostics, and offers multiple communication options.

Typical Applications:

The ADrive 4B055 is an excellent choice for:

• Residential Elevators: Apartment buildings, multi-story homes.
• Light Commercial Elevators: Office buildings, hotels, retail spaces with moderate traffic.
• Modernization Projects: Replacing older, less efficient drives with a modern, energy-saving VVVF solution.
• Applications with 5.5kW Motors: Efficiently controls both asynchronous and synchronous motors within its power rating.

Frequently Asked Questions (FAQ) – Arkel ADrive 4B055

Q1: What motor size can the ADrive 4B055 handle?
A: It’s designed for elevator motors rated up to 5.5 kW (approximately 7.5 HP).

Q2: Can this drive operate a synchronous (gearless) motor?
A: Yes, but requires the separate purchase and installation of the Arkel ENCABIT-Plus module for absolute encoder (EnDat, SSI, SinCos) communication.

Q3: Does it work with standard induction (asynchronous) motors?
A: Yes, it can control asynchronous motors in both closed-loop (with an incremental encoder) and open-loop (V/F control, no encoder needed) modes.

Q4: What is the required input power supply?
A: A 3-phase AC supply voltage between 340V and 420V.

Q5: Does it include the Anti-Rollback feature?
A: Yes, the ADrive 4B055 incorporates the start-hold (anti-rollback) function to prevent unwanted car movement when the brakes release.

Q6: Is a braking resistor included?
A: No. Braking resistors must be chosen based on the specific elevator’s characteristics (load, speed, duty cycle) and purchased separately. Consult the ADrive documentation for selection guidance.

Q7: Can I configure this drive remotely?
A: Yes, using the optional Arkel SCR01 ADrive Remote Keypad accessory, which connects via a standard network cable.
