Shenzhen Veikong Electric CO,Ltd. a high-tech enterprise which has
been specializing in researching, manu
facturing and trading high, medium and low voltage inverter as well
as bypass contactor soft starter, providing our
clients with integrated system solutions. We have professional
R&D and devoted management team with more than
20 years' experience of theoretical research, product development
and quality management. Veikong is also one of
the first independent AC drives company in China. We adopt SPWM,
sensorless vector control and vector and torque
control technology in our VFD series, which has reached the
international advanced standard. The products can
directly replace and be equivalent of Europe and the United States,
Japan and other brands, providing customers
with a powerful technical support.
Features of VEIKONG solar pump inverter:

3. VEIKONG Manufacturing Enviroment
For 220V single phase motor connection
1: Single phase asynchronous motor wiring method (without
starting capacitor):
Notice: U is connected to the common end of the starting winding
and the working
winding, V is connected to the starting winding, and W is connected
to the working
winding;
Single-phase asynchronous motor if the rotary steering is not
correct, you can
change the V and W wiring or set P22.13=1.
First solution: Set parameter P11.01=1 (Single phase motor type
without capacitor) or
second solution: set P00.11=00031 if your motor frequency is 50 hz
or set P00.11=32 if
your motor frequency is 60HZ
2: Single-phase asynchronous motor wiring method (with capacitor)
Notice1:First solution: Connect motor cable to power terminal U and
W and enter BSC
mode to Set parameter P23.15=0(output phase loss shielding
protection) or second
solution: set macro P00.11=00021 if your motor frequency is 50HZ or
set P00.11=22 if
your motor frequency is 60HZ
