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 ^ 217
1 Quadrac Square-law characterisc for drives with a square-law load torque over
the speed.
•
Squar
e-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 y
our pump drive or fan drive is not suitable for operaon with a
squar
e-law V/f characterisc, use the linear V/f characterisc instead.

characterisc for being adapted to special load proles.
3 Eco Linear characterisc with energy opmisaon in the paral load opera-
onal range.
13.4.3.1 Linear V/f
characterisc
The linear V/f characterisc leads to a constant torque.
13.4.3.2 Square-law V/f characterisc
The square-law V/f characterisc is typically used in heang, venlaon and climate applica-
ons to control the speed of fans and pumps.
