Available at ISF Elevator Shop, it combines sophisticated vector control algorithms with crucial elevator-specific safety and comfort features.

Key Features & Benefits (ADrive 4B075):

• Optimized for 7.5kW Motors: Perfectly scaled to control elevator motors up to 7.5 kW (~10 HP), delivering reliable performance and efficiency.
• Exceptional Ride Quality: Guarantees smooth acceleration, deceleration, and constant speed travel using precise VVVF vector control, significantly reducing noise and vibrations. Incorporates the vital Anti-Rollback function for seamless starting.
• Energy Savings: Reduces elevator energy consumption compared to conventional drives, contributing to lower operating expenses.
• Accurate Speed & Leveling: Maintains precise speed profiles regardless of load, ensuring accurate floor leveling and passenger comfort.
• Broad Motor Compatibility: Designed to operate both traditional Asynchronous (Induction) motors (open/closed loop) and modern high-efficiency Synchronous (Gearless) motors (closed loop, requires optional ENCABIT-Plus module for absolute encoders).
• Emergency Evacuation Support: Capable of performing emergency rescue operations during power outages when powered by an external 24VDC control supply and a suitable battery (60-120V) or UPS system.
• Comprehensive Protection Features: Integrates multiple protection mechanisms including overcurrent, over/undervoltage, short circuit, phase loss, thermal protection (drive and motor via PTC input), ensuring system safety and longevity. EMC certified.
• Intuitive Operation: Features a clear LCD screen and a 5-key keypad for straightforward parameter adjustments, system monitoring, and diagnostics, using standard elevator units.
• Advanced Capabilities: Supports auto-tuning, logs the last 256 faults, and offers various communication interfaces for integration.

Typical Applications:

The ADrive 4B075 is well-suited for:

• Standard Residential Buildings: Multi-floor apartment complexes.
• Commercial Properties: Office buildings, hotels, shopping centers with moderate passenger flow.
• Modernization Projects: Efficiently replacing older drive systems to enhance performance and reduce energy consumption.
• Applications with 7.5kW Motors: Reliably controls both asynchronous and synchronous motors within its power capacity.

Frequently Asked Questions (FAQ) – Arkel ADrive 4B075

Q1: What is the maximum motor power for the ADrive 4B075?
A: This inverter is designed for elevator motors rated up to 7.5 kW (approximately 10 HP).

Q2: Do I need an extra module to use this with a gearless (synchronous) motor?
A: Yes, the Arkel ENCABIT-Plus module must be purchased and installed separately to connect the necessary absolute encoder (EnDat, SSI, or SinCos) required by synchronous motors.

Q3: Can it run a standard induction motor without an encoder?
A: Yes, the ADrive 4B075 supports open-loop V/F control for asynchronous (induction) motors, which does not require an encoder.

Q4: What voltage does it operate on?
A: It requires a 3-phase AC power supply between 340V and 420V.

Q5: Does it prevent rollback when the brake opens?
A: Yes, it features the integrated Anti-Rollback (start-hold) function for smooth starts without unwanted movement.

Q6: Is a braking resistor necessary?
A: Yes, in most elevator applications, a braking resistor is required to dissipate regenerated energy during deceleration. It must be selected according to the elevator’s specifications and purchased separately.
