5.13 Setting User-Defined Functions
5-36
Setting Operand Parameters
The parameters that you need to enter depend on whether the function is followed by "( , )"
or "( )".
• Setting parameters for functions followed by "( , )"
Specify the element to the left of the comma, and specify the harmonic order to the
right of the comma. For example: (E1,OR2).
• Symbols used to represent elements
E1 to E3: Element 1 to element 3
E4: Σ
• Symbols used to represent harmonic orders
ORT: Total
OR0: DC
OR1: Fundamental signal
OR2 to OR50: Harmonics
* The harmonic measurement feature (optional) is required.
• Setting parameters for functions followed by "( )"
Specify the element. You do not need to specify a harmonic order. For example: (E1).
For information about the symbols that can be used in the parameters of each operand,
see appendix 7.
Values Substituted in Operands
• The substituted value of TI() is the same regardless of which element symbol (E1 to
E3) is used in TI(). The unit of TI values is seconds.
• The U1 in PHIU1U2 represents the voltage signal of the element whose element
number is the smallest in the wiring unit (Σ). For example, if input elements 2 and 3
are assigned to wiring unit Σ, PHIU1U2 is the phase difference between the voltage
signals of input elements 2 and 3.
