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 param-
eterized
Starting Voltage 600 (US), the linear equation of the V/f-characteristic re-
sults.

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.

15.1 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 (parame-
ter
Operation Mode 670). The output voltage value resulting from the V/f character-
istic is changed by addition of the calculated voltage pre-control.
