Technical Specifications

Function and Working Principle

The ATV320U02M2B regulates motor speed by converting a fixed-frequency AC input into a variable-frequency output that matches the operational requirements of the connected motor.

Its operating sequence can be summarized as:

AC Input Power → Rectifier → DC Link → IGBT Inverter → Variable Frequency AC Output → Motor

Through continuous monitoring of motor parameters, the drive automatically adjusts output voltage and frequency to maintain smooth operation under varying load conditions.

Major control functions include:

• Precise speed regulation
• Stable low-speed operation
• Smooth acceleration and deceleration
• High starting torque
• Reduced mechanical vibration
• Improved energy efficiency
• Enhanced motor protection

Advanced digital control technology enables excellent machine performance while minimizing energy consumption and equipment wear.
