User-definable V/f characteristic
The "user-definable V/f characteristic" is provided for the individual adjustment of the motor
magnetisation to the actual application if linear and square-law characteristics are not suita-
ble.
•
The characteristic is defined by means of 11 parameterisable grid points (voltage/
frequency values).
•
In the Lenze setting the 11 grid points represent a linear characteristic:
