Vector V/f control (r0108.2 = 0) 5.2 Voltage boost

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.

Permanent voltage boost (example: p1300 = 0 and p1310 > 0)

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).
