 English term or phrase: frequency Up/Down (controllo in frequenza unit¨¤ interna di condizionamento) PI Control (Determine ***Frequency Up/Down*** by ∆D Signal) 1. P control Calculate a total of the ∆D value in each sampling time (20 seconds), and adjust the frequency according to its difference from the frequency previously calculated. 2. I control If the operating frequency is not change more than a certain fixed time, adjust the frequency up and down according to the ¦²∆D value, obtaining the fixed ¦²∆D value. When the ¦²∆D value is small...lower the frequency. When the ¦²∆D value is large...increase the frequency. 3. Limit of frequency variation width When the difference between input current and input current drooping value is less than 1.5 A, the frequency increase width must be limited. 4. Frequency management when other controls are functioning  When each frequency is drooping; Frequency management is carried out only when the frequency droops. traduzione del titolo "Controllo PI (proporzionale integrale)- Determinazione delle ***variazioni di frequenza*** in base al segnale ∆D"
