Output side earth (ground) fault overcurrent protection

1. How much is the sensitivity current? When the sum of the three-phase output current of the inverter reaches approximately 70% of the inverter rated curren... More Details >>

Soft-PWM

The inverter uses PWM control to change the output voltage and frequency to vary the motor speed. PWM stands for Pulse Width Modulation. Voltage is chopped i... More Details >>

Rotation speed setting

1. The inverter display is based on the frequency, and the speed and moving speed are displayed by converting the frequency into the corresponding value. The... More Details >>

Speed change due to power supply voltage fluctuation

1. The output frequency satisfies the "control specification/frequency precision" even when the power supply voltage changes, but the output voltage cannot r... More Details >>

Controlling multiple VVVFs via communication from personal computer

To control multiple inverters using arbitrary signals (4 to 20 mA) simultaneously, it is recommended to connect the signals (4 to 20 mA) in series. (This doe... More Details >>

Brake resistor

Connecting the brake resistor allows for quick deceleration because the regenerative power is processed. (The brake torque increases.)Therefore, when an exte... More Details >>
