User-Defined Functions (User Defined Functions)
You can combine function symbols to create equations and use the numeric data of the combined functions to
determine the value of the equation.
User-defined functions allow you to determine physical values other than those of the measurement functions
by combining operands. The measurement functions that you can specify for the
at power and motor output. However, by using user-defined functions, you can create equations consisting of
measurement functions other than power and motor output measurement functions to determine ratios other
than efficiency.
Selecting Which User-Defined Function to Configure
Select the number of the user-defined function that you want to configure from the options below.
• F1−F5: User-defined functions F1 to F5
• F6−F10: User-defined functions F6 to F10
• F11−F15: User-defined functions F11 to F15
• F16−F20: User-defined functions F16 to F20
