7.4.2.2 Motor parameters’ setting by manual
If inverter alarm malfunction and cannot pump water caused by mismatching parameters
during the first commissioning, setting motor parameters by manual is required.
First step: Stop inverter;
Second step: refer to “8.3.5.3 Key Parameters of the System Set ” to change
“MP-Sel” to “manual”;
Third step: Press “ENTER” and “DOWN“ at the same time to return to the first screen.
Note！
a) This four parameters of “R-Stat”, “R-Rotr”, “L-Mutu”, “L-Leak” in the setting
menu are default;
b) If start the inverter based on those default, but it occurs output current
exceed motor rated current by 4%, and output power is less than 50%, and the
output frequency is normal, that means “R-Stat” is bigger. Solution: Stop
inverter, enter into setting menu to reduce “R-Stat” by 10%, and try again. If it
still cannot work, reduce by 10% every time till system can run well (40%
max.).
c) If it occurs output current is big, but output frequency is low, and no water
output, which may caused by the mismatching of “R-Stat” and “L-Mutu”.
Solution: Stop inverter, enter into setting menu to reduce “R-Stat” and “L-Mutu”
by 10% respectively, and try again. If it still cannot work, reduce both by 10%
every time till system pump water (40% max.). If it occurs situation b) at this
time, please refer to b) solution to solve it.
d) If it occurs abnormal during the first commissioning, please refer to “9.1
Troubleshooting” for reason.
