Functions
Operation Frequency Function
This function makes calculations for two inputs and reflects the result as the output frequency.
•Inputs FV and FI cannot be set simultaneously. Do not connect the signal lines for inputs FV and
FI simultaneously.
Frequency Addition Function
This function adds or subtracts the constant frequency set in A145 to/from the output frequency.
Select addition or subtraction in A146.
•Inputs FV and FI cannot be set simultaneously. Do not connect the signal lines for inputs FV and
FI simultaneously.
