6.6.2.1

Defining a user-defined V/f characteristic

To individually adjust the motor magnetisation to the real application, a user-definable

characteristic can be selected in

C00950

if the linear and square-law characteristic are not suitable.

• The interpolation points (voltage/frequency values) of this characteristic are selected via the 11

subcodes of

C00952

and

C00953

.

• If less interpolation points are required, the interpolation points that are not needed have to be

deactivated via the subcodes of

C00954

.

• In the Lenze setting the 11 grid points represent a linear characteristic:
