5.4.1 Water discharge speed PI adjustment
If you have higher requirements on the water discharge speed, you can adjust the PI
parameters (P15.06–P15.10) appropriately. Setting the PI parameters to larger values
will result in a faster water discharge speed, but the motor frequency fluctuates greatly;
conversely, setting the PI parameters to smaller values will result in a slower water
discharge speed, but the motor running frequency is relatively smooth.
