U1 and V1 are common ends of winding to connect with W phase output of solar Pump
inverter, connect U2 end of running winding to U phase output and connect V2 of starting
winding to V phase output.
After adjustment of positive way, change the running direction by F00.13 as same with
positive/negative way control of three phase motor.
