Name Description
Set the Inverter input voltage in
1 volt.
This setting is used as a refer-
ence value in protection func-
tions.
0 to E: Select from the 15
preset patterns.
F: Custom user-set patterns
(Applicable for settings
E1-04 to E1-10.)

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 disregarded.
Always ensure that the four fre-
quencies are set in the following
manner:
E1-04 (FMAX) ≥ E1-06 (FA) >
E1-07 (FB) ≥ E1-09 (FMIN)
