Set the Inverter input voltage in 1
volt.
This setting is used as a reference
value in protection functions.
0 to E: Select from the 15 preset
patterns.
F: Custom user-set patterns
(Applicable for settings E1-04
to E1-10.)
Output voltage (V)
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 fre-
quencies are set in the following
manner:
E1-04 (FMAX) ≥ E1-06 (FA) > E1-
07 (FB) ≥ E1-09 (FMIN)
