1). Ensure wiring is done as per Figure7-3, check and confirm the wirings to be correct, and then close
Q1.
2). Setting the Motor Parameters
Set the parameter d0.01 ~ d0.05 as per name plate details of motor
3). Testing the water yield of pump
Press the operation key “RUN”, under normal circumstance of light strength, if the operation frequency
is low or water yield is less, then check the direction of rotation of motor
4). System Effluent Speed: PI regulation
If the user has a high requirement for the effluent speed, PI parameters can be regulated appropriately
(y0.09
~
y0.10). For larger value of PI parameter, higher effluent speed can be achieved but it will also
lead to fluctuation in motor frequency; Smaller PI value will give steady and slow water effluent speed
with more steady frequency of motor operation.
