Seng can only be changed if the inverter is inhibi-
ted.
Selecon of the V/f characterisc shape for the adaptaon to dierent
load proles.
0 Linear Linear characterisc for drives with constant load torque over the speed.
4Linear V/f characterisc ^ 178
1 Quadrac Square-law characterisc for drives with a square-law load torque over
the speed.
•
Square-law V/f characteriscs are preferably used for centrifugal
pumps and fan drives.
•
Please always check whether the corresponding drive is suitable for
operaon with a square-law V/f characterisc!
•
If your pump drive or fan drive is not suitable for operaon with a
square-law V/f characterisc, use the linear V/f characterisc instead.
