Functions
Operation Frequency Function
This function makes calculations for two inputs and reflects the result as the output frequency.
•Inputs O and OI cannot be set simultaneously. Do not connect the signal lines for inputs O and OI
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.
TAllocate 50 to multi-function input terminal on parameter C001 to C005 to use this functions.
