Configuring a reference frequency
[ 1 ] Using and keys (F01 = 0 (factory default) or 8)
(1) Set function code F01 at "0" or "8" ( / keys on keypad). This cannot be done when the keypad is in
Programming or Alarm mode. To enable frequency setting using the and keys, first place the keypad in
Running mode.
(2) Press the or key. The 7-segment LED monitor displays the reference frequency and the LCD monitor
displays the related information including the operation guide, as shown below.
Example of Reference Frequency Configuration Screen
(3) To change the reference frequency, press the or key again. To save the new setting into the
inverter's memory, press the key (when E64 = 1 (factory default)). When the power is turned ON next time,
the new setting will be used as an initial reference frequency.
In addition to saving with the key described above, "Automatic saving when the main power is turned
OFF" is also possible (when E64 = 0).
When you start accessing the reference frequency or any other parameter with the and keys,
the least significant digit on the display blinks and starts changing. As you are holding down the key,
blinking gradually moves to the upper digit places and the upper digits becomes changeable.
Pressing the key moves the changeable digit place (blinking), making it easy to change upper
digits.
Setting function code C30 at "0" (Enable / keys on the keypad) and selecting frequency
command 2 as a frequency command source makes it possible to access the reference frequency in
the same manner using the and keys.
If you have set function code F01 at "0" ( / keys on keypad) but have selected a frequency
command source other than frequency 1 (i.e., frequency 2, via communications link, or as a
multi-frequency), then using the or key cannot change the frequency command even if the
keypad is in Running mode. Pressing either of these keys just displays the currently selected
frequency command.
Setting function code F01 at "8" ( / keys on keypad) enables the balanceless-bumpless
switching. When the frequency command source is switched to the keypad from any other source, the
inverter inherits the current frequency that has applied before switching, providing smooth switching
and shockless running.
When the frequency command source is other than the digital reference setting, the LCD monitor
displays the following.
Keypad takes precedence.
The lowest digit blinks.

Keypad is not enabled.
Setting on the analog terminal [12] is
effective. (See the table below.)
