Ƶ
Digital Setting (Non-retentive at Power Down)
The initial value of frequency reference is F0-08 (Preset frequency). You can modify
frequency reference by pressing
and
on the operating panel (or using the UP/
DOWN function of input terminals).
When the AC drive is powered on again, frequency reference continues from the value of
F0-08.

Digital Setting (Retentive at Power Down)
The initial value of frequency reference is F0-08 (Preset frequency). You can change
frequency reference by pressing
and
on the operating panel (or using the UP/
DOWN function of input terminals).
When the AC drive is powered on again, frequency reference continues from where it last
reached.

50.00 Hz
F0-10
Max. frequency
50.00 to 500.00 Hz
50.00 Hz
Note
F0-23 (Retentive selection of digital setting frequency upon stop) determines
whether to save frequency reference selection by pressing
and
or
via the up/down function when the AC drive stops. It is not the same as F0-
03 = 0 or 1, which determines whether to retain the setting on power-off.

F0-23
Retentive selection of digital
setting frequency upon stop
0: Not retentive
1: Retentive
50.00 Hz
F0-23 is valid only when frequency reference setting channel is digital setting.
Ɣ
F0-23 = 0: Non-retentive
The AC drive resumes frequency reference to the value set in F0-08 at stop.
Frequency reference continues from the value of F0-08 at next power-on.
Ɣ
F0-23 = 1: retentive
The AC drive retains the frequency reference that was last reached at stop. Frequency
reference continues from the retained value at next power-on.
For example, F0-08 is set to 40 Hz and you increase it to 45 Hz
by pressing
. If
F0-23 = 0, The
drive resumes frequency reference to 40 Hz after stop.
If F0-23 = 1,
frequency reference remains at 45 Hz after stop.
