Starting boost (entered in %)

0.0 %

Voltage boost when starting (after an ON command) when using the linear or square-law V/f characteristic as a % relative to P0305 (rated motor current) or P0350 (stator resistance). The voltage boost remains active until

1)the setpoint is reached for the first time and

2)the setpoint is reduced to a value that is less than the instantaneous ramp-function generator output.
