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
