Common Settings Of V/F Curve - Delta C2000 series User Manual

Pr.01-35 to Pr.01-42 is the V/f curve for the motor 2. When multi-function input terminals
Pr.02-01~02-08 and Pr.02-26 ~Pr.02-31 are set to 14 and enabled, the AC motor drive will act as
the 2nd V/f curve.
The V/f curve for the motor 1 is shown as follows. The V/f curve for the motor 2 can be deduced
from it.
