Factory Setting: 0.00
Settings 0.00~600.00Hz
 These parameters are used to set the skip frequency of the AC drive. The skip
frequencies are useful when a motor has vibration at a specific frequency bandwidth.
By skipping this frequency, the vibration will be avoided.

Fmin (4th output frequency setting)
 When the frequency is less than Fmin (Pr.01-07 or Pr.01-41), it will operate by this
parameter.
 When it is set to 0, the AC motor drive will be in waiting mode without voltage output
from terminals U/V/W.
 When setting 1, it will execute DC brake by Vmin(Pr.01-08 and Pr.01-42) in V/f, VFPG
and SVC modes.
 When it is set to 2, the AC motor drive will run by Fmin (Pr.01-07, Pr.01-41) and Vmin
(Pr.01-08, Pr.01-42) in V/f, VFPG, SVC and FOCPG modes.
