Description
The Delta VFD-M Series VFD015M21A is a compact, high-performance AC motor drive engineered for low-horsepower industrial and commercial applications. Operating on single-phase 230V input power, this drive converts single-phase AC input into controlled 3-phase output to regulate the speed and torque of 1.5kW (2HP) induction motors.
Known for its ultra-compact design, low-noise operation, and reliable torque delivery, the VFD-M series is widely utilized in light machinery setups. For small manufacturers, machine builders, and workshop owners in Bangladesh where 3-phase power may not always be readily available, the VFD015M21A provides a dependable, energy-efficient solution to run 3-phase motors smoothly from a standard single-phase supply.
Key Features
- Single-Phase Input to 3-Phase Output: Enables running standard 3-phase 230V motors using single-phase 220V–240V utility power lines.
- Versatile Control Modes: Supports both V/F (Voltage-to-Frequency) control and sensorless vector control for stable speed regulation.
- Low-Noise Carrier Modulation: Operates with high carrier frequencies to minimize motor acoustic noise during operation.
- Integrated Keypad & Display: Includes an intuitive front-panel interface for straightforward parameter setup, speed adjustment, and status diagnostics.
- Compact Enclosure Chassis: Minimal panel footprint allows easy retrofitting inside small control boxes and compact machine frames.

Installation & Maintenance Guide
Installation Requirements
- Mount the drive vertically inside a clean, well-ventilated enclosure to ensure proper thermal convection.
- Keep adequate top, bottom, and side clearances around the unit as specified in the Delta VFD-M series manual.
- Wire input 1-phase AC lines to specified input terminals and 3-phase motor leads to output terminals U, V, and W.
- Ground the PE earth terminal properly to avoid static accumulation and reduce noise interference.
Maintenance Tips
- Inspect cooling vents periodically and remove dust or lint buildup using clean, dry compressed air every 3 to 6 months.
- Verify screw tightness on electrical power and control terminal blocks to avoid loose contacts caused by machine vibration.
- Keep ambient enclosure temperatures below 40°C for optimal component longevity.
Safety Instructions
- Always disconnect input AC mains power and wait at least 10 minutes for DC bus capacitors to discharge before touching electrical wires.
- Do not apply AC input power directly to output motor terminals U, V, and W.
- Installation, parameter tuning, and maintenance should be carried out by qualified electrical technicians.
