5.2 Set Frequency Reference
The AC drive provides the following four methods to output the required frequency reference:
●
Main frequency reference
●
Auxiliary frequency reference
●
Main & auxiliary calculation
●
Command frequency reference setting channel
5.2.1 Set Main Frequency Reference
Main frequency reference has nine setting channels.
F0-03 selects a required channel to set the main frequency reference, described in the following
figure.
Function Code Parameter Name Default
F0-03
Main frequency
reference setting
channel selection
Setting Range
0
0: Digital setting (non-retentive at power down)
1: Digital setting (retentive at power down)
2: AI1 3: AI2 4: Keyboard potentiometer
5: Pulse reference
6: Multi-reference
7: Simple PLC
8: PID reference
9: Serial comms.
■
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/YWN 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/YWN function of input
terminals).When the AC drive is powered on again, frequency reference continues from where it last
reached.

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.
Function Code Parameter Name Default
F0-23 Retentive selection of
digital setting frequency
upon stop
Setting Range
1 0: Not retentive
1: Retentive
F0-23 is valid only when frequency reference setting channel is digital setting.
●
F0-23 = 0: Non-retentiveThe 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.
●
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 re-
ference to 40 Hz after stop. If F0-23 = 1, frequency reference remains at 45 Hz after stop.
