Type of curve
The ‘Type of curve’ parameter defines the characteristic of the transmission characteristic curve
between setpoint value and setpoint position. The transmission characteristic curve is used to correct
the operating characteristic curve in order to guarantee a proportional flow relationship between the
setpoint value and the setpoint position.
