Setting the V/f Pattern
In
V/f control method, you can set the Inverter input voltage and the V/f pattern as the need arises.

Related Parameters
* 1. These
are values for a 200-V Class Inverter. Values for a 400-V Class Inverter are double.
* 2. The
factory setting will change when the control method is changed. (V/f control factory settings are given.)
* 3. The
contents of parameters E1-11 and E1-12 are ignored when set to 0.00.
* 4. E1-13
is set to the same value as E1-05 by autotuning.
* 5. When
C6-01 is set to 0, the upper limit of the setting range is 150.0 Hz.
* 6. For
(-E) models. Factory setting for base frequency is 50 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
