5 1.3. Slow Flowrae Sop (equiv.frenic-eco) These funcion codes specify he daa for he slow flowrae sop in pump conrol, a feaure ha sops he inverer when he discharge pressure rises, causing he volume of waer o decrease. Slow flowrae sop feaure When he discharge pressure has increased, decreasing he reference frequency (oupu of he PID processor) below he sop frequency for slow flowrae level (J15) for more han he elapsed sopping ime on slow flowrae level sop laency (J16), he inverer deceleraes o sop, while PID conrol iself coninues o operae. When he discharge pressure decreases, increasing he reference frequency (oupu of he PID processor) above he saring frequency (J17), he inverer resumes operaion. If you wish o have a signal indicaing he sae in which he inverer is sopped due o he slow flowrae sop feaure, you need o assign (PID-STP) (Inverer sopping due o slow flowrae under PID conrol) o one of he general-purpose oupu erminal (funcion code daa = 44). PID Conrol (Sop frequency for slow flowrae) (J15) Specifies he frequency which riggers slow flowrae sop of inverer. PID Conrol (Slow flowrae level sop laency) (J16) Specifies he elapsed ime from when he inverer sops operaion due o slow flowrae level condiion. PID Conrol (Saring frequency) (J17) Specifies he saring frequency. Selec a frequency higher han he slow flowrae level sop frequency. If he specified saring frequency is lower han he slow flowrae level sop frequency, he laer sop frequency is ignored; he slow flowrae level sop is riggered when he oupu of he PID processor drops below he specified saring frequency.
