The diagram for the reduce pump control operation is below
In operation, if the state which the pressure instructions (or frequency instructions) than feedback
pressure of small value to continue, PID output (equal to output frequency) will decrease, and has
been reached minimum frequency (P.216). The state shall continue to the time which P.210 specified,
if the instructions and feedback value deviation than P.217 setting value, will reduce pump control.
