POWER FUNCTIONS
Input (X1)
Touching Inp.1 opens the Tag name selector view. Select input signal used for the operating function.
Caution !
Be careful to choose a pen of Not Itself. For example, you cannot choose Function Pen 1 or the last
data of Function Pen 1 to be used as X1 in an equation for Function Pen 1. When assigning ‘last’ data
sample to X1, specify also the initial value. Otherwise no data is recorded for the first operating cycle.
The following combinations of X1 and A1 will result in an error and the screen will show ERR: X1 =
0 and A1<0, or X1 is negative and A1 is not integer.
When an calculation result is overrange (equal to ‘-1 x 10
10
’ or lower, and ‘1 x 10
10
’ or higher), the
screen will be blank. Such data cells are blank when converted into CSV.
Constant (A1)
Specify the exponent.
Constant
Exponent ±99.99
Initial value
Initial value is used in the function operation cycle as default data sample when ‘last’ data is specified in an equation.
If you do not need, leave the field blank.
Initial value
Max. 6 digits including a decimal point and minus sign
Caution !
(1) The power function results in error when:
X1 = 0, A1 < 0 or
X1 < 0, A1 ≠ integer
‘ERR’ is indicated on the screen.
(2) The power function results in overrange when the results exceeds the range from ‘-1x10
10
’ to ‘1x10
10
.’
No data is displayed on the screen, and CSV data cells are blank.
