* 1. These are values for a 200 V Class Inverter. Values for a 400 V Class Inverter are double.
* 2. E1-11 and E1-12 are disregarded when set to 0.0.
* 3. E1-13 is set to the same value as E1-05 by autotuning.

Description
Sets the Inverter input voltage.
This setting is used as a reference value
for protection functions.
0 to D: Select from the 14 preset
patterns.
F: Custom user-set pattern
(Applicable for setting of 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 disregarded.
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 to fine-adjust V/f for the out-
put range. Normally, this setting is not
required.
Sets the output voltage of the base fre-
quency (E1-06).
