Tayfun from TurkeyVeikong solar pump inverter is really in very good quality and we also prepared some promotional products for exhibition. We are going to make new orders soon. Last year there was only one local agent and this year, there are more than 8. Some of them only sell Veikong!
Cristian from ChileIt’s very good! LCD options make it much easier to use. That’s the strong point, easy of use. And robust. Great PC software.
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.

1. Wake up and sleep function parameters:
|P47.05||Light detection threshold||If the output frequency is lower than this value and exceeds P47.06, it will be reported to Sleep and stop||0Hz|
|P47.06||Light detection time||See P47.05 for explanation.||60s|
|P47.07||Light weak wake up time||After the sleep fault is reported, if the time when Vdc is higher than the undervoltage point is greater than the set value, the fault state is exited and the operation continues.||600s|
2. Dry runing protection function parameters:
|P24.12||Dry run/Unload protection option||
0: No offload detection is performed;
1: Enable dry run detection
|P24.13||Dry run/Unload detection level||
0.0 to 200.0%
The percentage of motor rated current.
|P24.14||Dry run Unload detection time||0.000s～60.000s||30.000s|
|P24.15||Unload detection offset frequency||
|P24.16||Reset time of dry run protection||0.0～6000.0||240.0s|
|P23.21||Dry run detection mode||
3000:Continue to run
3. Water full protection function parameters:
|P47.18||Full water level detection channel||
Note: DI terminal function code 60-full water level detection is same with Analogue detection, and the detection time and recovery time are the same.
|P47.19||Full water level detection value||
|P47.20||Full water level detection time||
When DI-60 is valid or meets the analog detection channel greater than P47.19 and maintains P47.20 time, the system reports A.Full and stops.
|P47.21||Full water recovery time||
When the condition described in P47.20 does not meet full water level detection requirement ,it will be returned to normal state after delay
Conditions for full water detection to take effect:
1. Any DI terminal set to No. 60 function receives the input switch closing signal.
For example, after P06.03 is set to 60, DI3 closes.
2. The analog input is greater than the detection value,
for example: set P47.18 = 1, P47.19 = 50%, then the AI1 input is greater than 5V or 10mA
3. After the condition 1 or 2 is met, continue to set the time at P47.20
And the system will report A.FULL Full water recovery conditions
4. The system enters the full water detection stage and displays A.FULL
5. When both conditions 1 and 2 are not met and the maintenance time is greater than the time set in P47.21, the system resumes.
