Functions
If only one frequency reference method is available, data is set using A001/A201 according to
the above table.
If a frequency is set in F001, the same value is automatically set in Multi-step Speed 1
Reference 0 (A020) (F001 = A020). If Motor 2 Control is enabled (SET input = ON), the same
value set in Multi-step Speed 2 Reference 0 is set (F001 = A220).
To switch between two frequency references by combining analog current/voltage switching
based on frequency reference specification via analog input (A001/A201 = 01), and the Digital
Operator with volume 3G3AX-OP01, allocate the FV/FI terminal (16: FV/FI) to a multi-function
input. The detailed setting method is explained below. (A005: FV/FI Selection)

Data is set using the control circuit terminal
(analog input signal).

Data is set using the Digital Operator or
Remote Operator (set frequency: F001).
03
Data is set via Modbus communication
(Modbus-RTU).
