F1.02 Start frequency holding time
Default0.0s Setting scope0.050.0s
Setting the appropriate starting frequency can increase the starting torque. Within start
frequency holding time (F1.02), the frequency inverter output frequency is the start
frequency, and then run from the start frequency to the target frequency, if the target
frequencyislessthanstartfrequency(F1.01),thefrequencyinverterwillnot
