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.
In V/f, VFPG and SVC modes
