Arkel ADrive 4B038 VVVF Inverter (3.8kW, 10A, 400V)

Optimize the performance and efficiency of your smaller elevator systems with the Arkel ADrive 4B038 VVVF Inverter. This specific model, rated for 3.8 kW power and 10 A nominal current at 400V, is the entry-level unit in the advanced ADrive series, available at ISF Elevator Shop. It brings sophisticated vector control, superior ride comfort, and essential safety features to lower-capacity elevator applications, providing a reliable and energy-efficient motor speed control solution.

Key Features & Benefits (ADrive 4B038):

• Optimized for 3.8kW Motors: Perfectly matched for controlling elevator motors up to 3.8 kW, ensuring efficient operation without oversizing.
• Enhanced Ride Comfort: Delivers exceptionally smooth acceleration, deceleration, and travel through precise VVVF control, minimizing noise and vibration. Features the Anti-Rollback function for seamless starts.
• Energy Savings: Vector control technology significantly reduces energy consumption compared to older drive systems, leading to lower operational costs.
• Precise Speed Regulation: Maintains accurate speed control regardless of load variations, ensuring precise floor leveling and consistent performance.
• Dual Motor Compatibility: Capable of driving both standard Asynchronous (Induction) motors (in open or closed loop) and modern Synchronous (Gearless) motors (closed loop only, requires optional ENCABIT-Plus for absolute encoders).
• Emergency Evacuation Ready: Designed to support emergency operation during power outages using external 24VDC control power and a compatible battery pack (60-120V) or UPS system (connection to L1/L3 terminals).
• Comprehensive Protections: Includes built-in protection against overload, over/undervoltage, short circuits, phase loss, overheating, and more, ensuring drive and motor safety. EMC test certified.
• User-Friendly Interface: Features an integrated LCD screen and 5-key keypad for straightforward parameter setup, diagnostics, and monitoring using elevator-specific units (m, m/s).
• Advanced Capabilities: Offers features like auto-tuning (static for synchronous motors), detailed fault history (last 256 errors), PTC input compatibility, and communication options.

Typical Applications:

The ADrive 4B038 is ideal for:

• Low to Medium Capacity Elevators: Residential buildings, small commercial properties, platform lifts requiring precise control.
• Modernization Projects: Upgrading older elevator systems with inefficient drives to improve performance and reduce energy use.
• Applications with 3.8kW Motors: Controlling both asynchronous and synchronous motors within its power rating.

Frequently Asked Questions (FAQ) – Arkel ADrive 4B038

Q1: What size elevator motor is the ADrive 4B038 suitable for?
A: It’s designed for elevator motors rated up to 3.8 kW (approximately 5 HP).

Q2: Can I use this drive with a gearless (synchronous) motor?
A: Yes, but you will need the optional Arkel ENCABIT-Plus module to connect the required absolute encoder (EnDat, SSI, or SinCos).

Q3: Can I use this drive without an encoder (open loop)?
A: Yes, but only with asynchronous (induction) motors. Open loop V/F control is available for these motor types. Synchronous motors always require closed-loop control with an encoder.

Q4: What is the input voltage requirement?
A: It requires a 3-phase AC supply between 340V and 420V.

Q5: Does it have an anti-rollback feature?
A: Yes, the ADrive series includes an integrated anti-rollback function (start-hold) which helps prevent unwanted car movement when the brake is released, enhancing start smoothness.

Q6: Is it easy to configure?
A: Yes, it has a user-friendly LCD display and keypad with menus specifically designed for elevator parameters (using units like m/s). PC software (ADrive-Win) is also available for configuration and monitoring. Auto-tuning features simplify motor setup.

Q7: Does this model include a braking resistor?
A: No, braking resistors are typically selected based on the specific elevator application (duty cycle, load, speed) and are sold separately. Refer to the ADrive manual for guidance on selecting the correct resistor.
