H Setting a User-defined V/f Pattern (Setting “F”)
Parameters
E1-04 through E1-10 can be set by the user when E1-03 has been set to “F
.” These param
-
eters
are read-only when E1-03 isn’t set to “F
.” Parameters E1-04 through E1-10 cannot be changed
during operation.
When
making the V/f characteristics a straight line,
set the same value in E1-07 (middle output frequen
-
cy)
and E1-09 (minimum output frequency). In this case, parameter E1-08 (middle output voltage) will
be ignored.

Note 2. These voltages are for the 200-V class; Double the voltage for 400-V class Inverters.
Note 3. The
default
setting depends on the Inverter
’
s capacity
. The default settings shown in the table
are
for 200-V class, 0.4 to
1.5 kW Inverters. Refer to the graphs for “Setting: 1” on pages
5-26
and 5-27 for the default settings in 2.2 to 45 kW and 55 to 300 kW Inverters.
Note 4. The default settings for E1-07 through E1-10 depend on the control mode. The default
set
-
tings shown in the table are for V/f control.
Note 5. The four frequency settings must satisfy the following formula:
E1-04 (F
MAX
) ≥ E1-06 (F
A
) > E1-07 (F
B

For flux vector control, make the settings as follows:
