Item Setting result
Logarithmic The start and end points are drawn by expanding or contracting the graph so that they will be the terminal points of the graph of logarithmic
function function y=log
*1
Sine function The start and end points are drawn by a sine function. The vertical width, A, of the sine function drawn is the value set by "Amplitude". The
star position can be changed by 180 by using "Phase setting".
Number of data in a wave pattern: Wx
Digital value range: Wy
Data position of the start point: Xst
Data position of the end point: Xed
Cosine The start and end points are drawn by a cosine function. The vertical width, A, of the cosine function drawn is the value set by "Amplitude".
*1
function The star position can be changed by 180 by using "Phase setting".
Number of data in a wave pattern: Wx
Digital value range: Wy
Data position of the start point: Xst
Data position of the end point: Xed
S-shaped The start and end points are drawn by S-shaped interpolation by using the following acceleration.
Acceleration a = (2 Output value width D)  (Data width C  Data width C)
interpolation
The digital value y of certain point x is calculated by the following formula.
If x < (c/2): y = ax
If x  (c/2): y = -a (x - c)
Width of output value: D
Data width: C
*1 When the sine and cosine functions are to be set, set the digital values of the start and end points to the same value.
