Brahim assad from SyriaVEIKONG VFD500 output frequency is stable when the others are fluctuating. Also output current is less than others, that’s why output frequency is higher too which can save more energy.

5. Technical Questions and solutions
1) How to achieve Automatic start after stop? If it is controlled by keyboard,so there is no need to set any parameter(P47.03 waiting time)If you want to control by external switch,First set P00.06=1 and use a wire or switch to connect com and DI1,When the switch is closed, the drive run, when the switch is open, the drive stop
2) How to use a float in the water tank to stop the pump if the tank is full? If your float signal is digital signal Use float switch to short DI 3 and com ,see diagram 1.3 15
3) Use level probe in the well for protection against dry running
1 st solution: See self learning of dry run(For LED display)
2 nd solution: do it manually Set P24.13=30%-60%(as per real empty load current percentage based on rated current) and P24.14 P24.16 and P23.21
3 rd solution: If your sensor is digital switch ,just short D4 and com
4 th solution:If your float signal is Analog signal, Connect Ai2 and 10V and GND and set P41.00=23 and P41.03-P41.06
