Note
Avoid thermal overload
If the voltage boost value is too high, this can result in a thermal overload of the motor
winding.
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.

Permanent voltage boost (example: p1300 = 0, p1310 >0, p1311 = p1312 = 0)
