Frequency (Hz)
To set V/f characteristics in a straight line, set the same values for
E1-07 and E1-09. In this case, the setting for E1-08 will be disre-
garded.
Always ensure that the four frequencies are set in the following
manner:
E1-04 (FMAX) ≥ E1-06 (FA) > E1-07 (FB) ≥ E1-09 (FMIN)
Set only when V/f is finely adjusted at rated output range.
Adjustment is not normally required.
