 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.

0.00–599.00 Hz
 If the output frequency setting is higher than the upper limit (Pr.01-10), the drive runs with the
upper limit frequency. If the output frequency setting is lower than the lower limit (Pr.01-11) but
higher than the minimum output frequency (Pr.01-07), the drive runs with the lower limit
frequency. Set the upper limit frequency > the lower limit frequency (Pr.01-10 setting value must
be > Pr.01-11 setting value).
 If the PID feedback control is enabled for the drive, the drive’s output frequency may exceed the
Frequency command but is still limited by this setting.
