(3) High starting torque
Start-Up Frequency
Settings
 When the starting frequency is higher than the minimum output frequency, the drives' output is
from the starting frequency to the setting frequency. Refer to the following diagram for details.
Fcmd: frequency command
Fstart: start-up frequency (Pr. 01-09)
fstart: actual start-up frequency of drive
Fmin: 4th output frequency setting (Pr. 01-07/ Pr. 01-41)
Flow: output frequency lower limit (Pr. 01-11)
 When Fcmd > Fmin and Fcmd < Fstart:
If Flow < Fcmd, drive runs directly by Fcmd.
If Flow ≥ Fcmd, drive runs by Fcmd, then rises to Flow according to acceleration time.
 The output frequency goes directly to 0 when decelerating to Fmin.
0.00–599.00Hz
