About the converter mode
●
The VF66R converter provides the PWM sine wave mode and 120-degree conduction mode.
About the cooling fan
●
When the converter is turned on, the cooling fan installed on it also starts at the same time.
●
It behaves as follows:
･
Power-on: It operates for five minutes after power-on and then stops. However, when the converter is operated within
