V / f characteristic
The values of the V / f characteristic (P0181 – P0188) are calculated from
the rating plate data (P0181 – P0188). The unit calculates the
characteristic data after you have entered the data on the rating plate of
your motor. You can then modify and optimize the characteristic values. If
you subsequently change the rating plate data again, this will cause
recalculation of the characteristic data and your optimized data will be
overwritten.
Default calculation of the characteristic data from the rating plate data:
