2007 Inverting
adder
Inverting addition function with single input
(input 1).
This function subtracts the input 1 with the value
specified with the 1st function code, inverts the
result. Furthermore, adds this result to the value
specified with the 2nd function code and outputs
the final result.

2008 Variable
limiter
Variable limit function of single input (input 1).
Input 1 provides upper limit value and input 2
provides lower limit value.

2009 Linear
function
Linear function of single input (input 1).
This function takes the single input (input 1)
value, calculates pre-defined first-order
polynomial, and outputs the result.
The 1st and 2nd function codes provide the
coefficients of the polynomial.
The polynomial is represented by the following
formula.
B A
K K y + χ × =
The output is limited within the range between
-9990 and 9990 by the internal limiter.

2051 Comparator
1
Comparison function with hysteresis.
This function compares the differential value
between input 1 and input 2 with the threshold
value specified with the 1st function code. The
2nd function code provides hysteresis width.
If the differential value is (threshold value +
hysteresis width) or bigger, this function outputs
logical “1: True”. On the other hand, if the the
differential value is (threshold value - hysteresis
width) or smaller, this function outputs logical
“0: False”.

2
Comparison function with hysteresis.
This function compares the differential value
between input 1 and input 2 with the threshold
value specified with the 1st function code. The
2nd function code provides hysteresis width.
If the differential value is bigger than (threshold
value + hysteresis width), this function outputs
logical “1: True”. On the other hand If the value
is smaller than (threshold value - hysteresis
width), the function outputs logical “0: False”.

3
Comparison function with hysteresis.
This function compares the absolute differential
value between input 1 and input 2 with the
threshold value specified with the 1st function
code. The 2nd function code provides hysteresis
width.
This function works like as comparator 1

Comparison function with hysteresis.
This function compares the absolute differential
value between input 1 and input 2 with the
threshold value specified with the 1st function
code. The 2nd function code provides hysteresis
width.

5
Comparison function with hysteresis.
Input 1 is the input value of this function and
input 2 is not used.
The 1st function code provides threshold value
and the 2nd one provides hysteresis width.
If input 1 is (threshold value) or bigger, this
function outputs logical “1: True”. On the other
hand if input 1 is smaller than (threshold value -
hysteresis width), this function outputs logical
“0: False”.
