● When the starting frequency (Pr.01-09) is larger than the Minimum Output Frequency of Motor 1 (Pr.01-07), the
drive’s frequency output starts when the starting frequency (Pr.01-09) reaches the F command. See the
following diagram for details.
● Fcmd = frequency command;
Fstart = start-up frequency (Pr.01-09);
fstart = actual start-up frequency of the 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, the drive runs directly with Fcmd.
– If Flow ≥ Fcmd, the drive runs with Fcmd, and then rises to Flow according to acceleration time.
● The drive’s output frequency goes directly to 0 when decelerating to Fmin.
