Basic Operation - Veichi SI23 Series Manual

Notes: Single phase motor has three lines, first use the multimeter check the three
lines resistor, the biggest value two lines parallel the start capacitor (recommend
the capacitor volume is 150UF/250V), the other line(common-coil) connect the
power terminal. Then use the multimeter check the common coil with the other two
lines resistor, the lower one connects another power terminal.

6. Basic Operation


Motor debugging
（1）AM Pump

Default parameter one key start and stop

Same power level, determine the direction of operation （F0.16）

Adjust motor parameters and corresponding protection parameters
according to the application
（2）PMSM Pump

Set motor parameter （F5.00-F5.06， Motor series 、 Frequency、 Speed、
Voltage、Current、Power）

Rotating self-tuningF5.12(SI22 SI30), F5.20 (SI23)

Judge the direction of the pump
（3）Single Phase Pump
 Connect the starting capacitor between the main coil and the auxiliary
coil
 Shield output phase loss
 Running judge the direction of the pump
