Defining a user-defined 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 suitable.
• 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:
