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
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
and
.
• If less interpolation points are required, the interpolation points that are not needed have to be
deactivated via the subcodes of
.
• In the Lenze setting the 11 interpolation points represent a linear characteristic:
