3.1.2.3 Setting the Main Frequency Through the Operating Panel
The main frequency can be set through the operating panel in two modes:
● F0‑23 = 0 (non‑retentive at power failure): When the AC drive is powered on again
after stop or power failure, the frequency value reverts to the preset value (F0‑08).
F0‑08 (preset frequency) can be changed by pressing the
or
key on
the operating panel or by using the UP/DOWN terminals. However, in this mode,
changes made to the frequency value will be cleared after the AC drive stops.
● F0‑23 = 1 (retentive at power failure): When the AC drive is powered on again after
power failure, the frequency reverts to the value set before power failure. F0‑08
(preset frequency) can be changed by pressing the
or
key on the
operating panel or by using the UP/DOWN terminals. In this mode, changes made
to the frequency value will be retained after the AC drive stops.
For example, assume that F0‑08 is set to 40 Hz and then increased to 45 Hz by
using the
key on the operating panel. If F0‑23 is set to 0 (non‑retentive), the
target frequency reverts to 40 Hz (value of F0‑08) after the AC drive stops. If F0‑23
is set to 1 (retentive), the target frequency is still 45 Hz after the AC drive stops.
