The default Cut-Off Voltage 603 (UC) and Cut-Off Frequency 604 (FC) are derived from the motor
data Rated Voltage 370 and Rated Frequency 375. With the parameterized Starting Voltage 600
(US), the linear equation of the V/f-characteristic results.

The Rise Frequency 602 (FK) is entered as a percentage of the Cut-Off Frequency 604 (FC), the
default value is f=10 Hz. The output voltage for the default Voltage Rise 601 (UK) is calculated as
U=92.4V.

17.1 Dynamic voltage pre-control
The Dyn. Voltage Pre-Control 605 accelerates the control behavior of the current limit controller
(parameter Operation Mode 610) and the voltage controller (parameter Operation Mode 670). The
output voltage value resulting from the U/F characteristic is changed by addition of the calculated
voltage pre-control.
