Setting sequence
1.If necessary, select V/f
characteristic (C014).
2.Select V/f-rated
frequency (C015).
-
The V/f-rated frequency determines the slope of the V/f characteristic and has
considerable influence on the current, torque and power performance of the motor.
-
An internal mains voltage compensation compensates deviations in the mains
during operation. They therefore do not have to be considered for the setting of
C015.
