* 1. These are values for a 200 V Class Inverter. Values for a 400 V Class Inverter are double.
* 2. The factory setting will change when the control method is changed. The V/f control factory settings are given.
* 3. When C6-01 = 1, the upper limit is 400.0.

To set V/f characteristics in a
straight line, set the same values
for E3-05 and E3-07.
In this case, the setting for E3-06
will be disregarded.
Always ensure that the four fre-
quencies are set in the following
manner:
E3-02 (FMAX) ≥ E3-04 (FA) >
E3-05 (FB) > E3-07 (FMIN)
