Note
The voltage boost affects all V/f characteristics (p1300).
NOTICE
If the voltage boost value is too high, this can result in a thermal overload of the motor
winding.

Voltage boost at acceleration (p1311)
Voltage boost at acceleration is effective if the ramp function generators provide the
feedback signal "ramp-up active" (r1199.0 = 1).
