• The motor runs in four quadrants, the torque, current, torque, and DC bus voltage respond quickly, and the motor runs stably.
• Smart AVR function, when the voltage automatic adjustment function is effective, as long as the minimum value of input voltage fluctuation is greater than the set output voltage (motor rated voltage), the output voltage can basically maintain the set value.
• The random carrier function can effectively reduce the noise of the motor and suppress the interference of the inverter to external equipment.

• Two acceleration modes, four acceleration and deceleration times, the time unit is 0.1s, the longest is 6500s.
• Simple PLC, automatic switching of running direction and frequency, to meet the requirements of on-site process.
• The software speed tracking ensures that the motor is started and the current speed is started, effectively avoiding the motor reverse rotation.
• DC braking provides leading torque, which is used to improve the stopping accuracy and realize fast stopping.
• Jump frequency, automatically adjust the output frequency outside the resonance frequency.

• Support derating operation of missing items and alarm of mechanical load damage.
• The advanced drive algorithm controls the output voltage and current, reducing the frequency of inverter fault protection.
• Overvoltage suppression. During deceleration, adjust the output frequency to avoid excessively high deceleration and cause the inverter bus voltage to be too high, thereby causing inverter overvoltage.
• Over-current suppression. During acceleration, the output frequency is adjusted to avoid excessive load caused by excessive deceleration, which may cause inverter over-current.
