select the input channel for main reference frequency of the inverter. There are eight
types of main reference frequency channels:
0: digital setup(non-recorded)
The initial value is the value of F0-11”Digital Setup Present Frequency”
It can change the setup frequency value of the inverter through the key ▲and
▼on the keyboard (or UP and DOWN of multifunction input terminals)
Non-recorded means that the setup frequency value is recovered to the value of
F0-11 Digital Setup Present Frequency”in case of inverter power supply failure.
1: digital setup (recorded)
The initial value is the value of FO-11 Digital Setup Present Frequency”
It can change the setup frequency value of the inverter through the key ▲and
▼on the keyboard (or UP and DOWN of multifunction input terminals)
Recorded means that the setup frequency upon restart of inverter due to power
failure remains the same
2：AI1
3：AI2
It means that the frequency is determined by the analog input terminal,
C220/C420Driver offers two analog input terminals ,that is ,A11and A12 ,and A11
