Arkel ADrive 4B110 VVVF Inverter (11kW, 26A, 400V)

Power your mid-range elevator applications with the robust and reliable Arkel ADrive 4B110 VVVF Inverter. This model, rated for 11 kW power and 26 A nominal current at 400V, represents a significant step up in capacity within the advanced ADrive series, available from ISF Elevator Shop. It delivers the sophisticated vector control, superior passenger comfort, and critical safety features expected in modern elevator systems.

Key Features & Benefits (ADrive 4B110):

• Optimized for 11kW Motors: Designed to efficiently control elevator motors up to 11 kW (~15 HP), making it ideal for standard commercial and larger residential buildings.
• Outstanding Ride Comfort: Ensures exceptionally smooth starts, stops, and travel using precise VVVF vector control, minimizing vibrations and operational noise, enhanced by the Anti-Rollback function.
• Significant Energy Savings: Reduces the elevator’s overall energy footprint compared to older technologies, leading to tangible savings on electricity costs.
• Accurate Performance: Maintains precise speed profiles and guarantees accurate floor leveling regardless of the elevator car’s load.
• Versatile Motor Compatibility: Fully capable of operating both traditional Asynchronous (Induction) motors (open/closed loop) and high-efficiency Synchronous (Gearless) motors (closed loop, requires optional ENCABIT-Plus module for absolute encoders).
• Emergency Ready: Supports essential emergency evacuation operations during power outages when configured with an external 24VDC supply and a compatible battery (60-120V) or UPS system.
• Built-in Protections: Features a comprehensive suite of protection functions (overcurrent, over/undervoltage, short circuit, thermal overload via PTC input, etc.) for maximum system safety and drive longevity. EMC certified.
• Easy Configuration & Monitoring: Equipped with an intuitive LCD screen and 5-key keypad for straightforward setup, parameter adjustments, and real-time monitoring using elevator-specific units.
• Advanced System Integration: Supports auto-tuning, detailed fault logging, and various communication options for seamless integration into the elevator control panel.

Typical Applications:

The ADrive 4B110 is a versatile choice for:

• Commercial Buildings: Offices, hotels, hospitals with standard capacity elevators.
• Larger Residential Complexes: High-rise apartment buildings.
• Modernization Projects: Upgrading existing elevators with 11kW range motors for improved efficiency and performance.
• Standard Capacity Passenger & Goods Lifts: Reliable control for elevators carrying typical loads.

Frequently Asked Questions (FAQ) – Arkel ADrive 4B110

Q1: What is the power rating of the ADrive 4B110?
A: This inverter is rated for 11 kW (approximately 15 HP) elevator motors.

Q2: Can I use this model for a gearless (synchronous) elevator motor?
A: Yes, however, you will need to purchase and install the Arkel ENCABIT-Plus module separately to connect the absolute encoder required for synchronous motor control.

Q3: Does it support standard asynchronous (induction) motors?
A: Yes, the ADrive 4B110 can control asynchronous motors using either closed-loop vector control (with an incremental encoder) or open-loop V/F control (without an encoder).

Q4: What input voltage is needed?
A: It requires a 3-phase AC power supply ranging from 340V to 420V.

Q5: Does it help prevent rollback on startup?
A: Yes, the ADrive 4B110 includes the Anti-Rollback (start-hold) feature, which minimizes unwanted car movement when the brake is released.

Q6: Is a braking resistor supplied with the drive?
A: No. A suitable braking resistor must be selected based on the elevator system’s parameters (energy regeneration potential) and purchased as a separate item. Refer to Arkel documentation for proper sizing.
