Adder
Inputs 1 and 2 are added and output. The upper limit
value and lower limit value can be set with function 1
and 2.

Subtracter
Subtraction function with two inputs (input 1 and input
2). This function has output limiters (upper/lower)
specified with two function codes.
The 1st function code provides upper limit value and
the 2nd one provides lower limit value.

2003
Multiplier
Multiplication function with two inputs (input 1 and
input 2). This function has output limiters (upper/lower)
specified with two function codes.
The 1st function code provides upper limit value and
the 2nd one provides lower limit value.

2004
Divider
Input 1 is divided by input 2 and output. This function
has output limiters (upper/lower) specified with two
function codes.
The 1st function code provides upper limit value and
the 2nd one provides lower limit value.

Lower limit
2005
Limiter
An upper/lower limiter is applied to input 1. This
function has output limiters (upper/lower) specified
with two function codes.
The 1st function code provides upper limit value and
the 2nd one provides lower limit value.
If the upper and lower limit values are the same, the
input value is output as is (limited in -9990 to 9990
range).

Absolute
value
Absolute value function of single input (input 1).
Negative input numbers become positive. This
function has output limiters (upper/lower) specified
with two function codes.
The 1st function code provides upper limit value and
the 2nd one provides lower limit value.
Upper limit
Lower limit
2007
Inverting
adder
Inverting addition function with single input (input 1).
This function subtracts the input 1 to the value
specified with the 1st function code, inverts the result.
And furthermore, the function adds the result to the
value specified with the 2nd function code and outputs
the result.

Variable
limiter
Input 1 is output as the upper limit value, and input 2
is output as the lower limit value for the step specified
with function 1. The lower limit value is not used if the
upper limit value is less than the lower limiter.

Linear
function
(Constant
setting)
Linear function of single input (input 1). Set with KA as
function 1, and KB as function 2. The output is limited
within the range between -9990 and 9990 by the
internal limiter.
