amplitude of the PID regulator on the output frequency command is maximum frequency (the
integral and differential functions are neglected).
Integration time I: It decides the speed of PID regulator adjusting the deviation between the
PID feedback quantity and the reference quantity. Integration time is the time within which
the integration regulator (the proportional and differential functions are neglected) performs
continuous adjustment and the adjustment quantity reaches maximum frequency (F0-09) when
the deviation between the PID feedback quantity and reference quantity is 100%. The shorter
