Note
Avoid thermal overload
If the voltage boost value is too high, this can re
sult in a thermal overload of the motor
Permanent voltage boost (p1310)
The voltage boost is active across the entire frequency range up to the rated frequency f
n
; at
higher frequencies, the value decreases continuously.
