Chapter 4 Parameters

 

2

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.
