9-28 Function Parameters
AC10 Inverter
0-5V and the output frequency is 10-120Hz.
AO1 output compensation is set by F426. Analog excursion can be compensated by setting
F426.
F428 AO2 lowest corresponding
frequency (Hz)
F429 AO2 highest corresponding
frequency (Hz)
F430 AO2 output compensation (%)
The function of AO2 is the same as AO1, but AO2 will output current signal, current signal of 0-
20mA and 4-20mA could be selected by F427.
F431 AO1 analog output signal
0: Running frequency;
1: Output current;
2: Output voltage;
3: Analog AI1;
4: Analog AI2;
6: Output torque;
7: Given by PC/PLC;
8: Target frequency
F432 AO2 analog output signal
When output current is selected, analog output signal is from 0 to twice rated current.
When output voltage is selected, analog output signal is from 0V to rated output voltage.
F433 Corresponding current for full
range of external voltmeter
0.01~5.00 times of rated current
F434 Corresponding current for full
range of external ammeter
In case of F431=1 and AO1 channel for token current, F433 is the ratio of measurement range
of external voltage type ammeter to rated current of the inverter.
In case of F432=1 and AO2 channel for token current, F434 is the ratio of measurement range
of external current type ammeter to rated current of the inverter.
For example: measurement range of external ammeter is 20A, and rated current of the inverter
is 8A, then, F433=20/8=2.50.
The greater the value of F437, the more stable the analog monitoring will be, but the slower
the response speed will be. Adjust the filter according to the actual system requirements.
