BITCLEAR
Clear the B bit of the A
parameter, BITCLEAR(A,
B). Output the changed
value after clearing the B
bit to input at A.
The input value of B must
be between 0
– 16. If the
value is higher than 16, it
will be recognized as 16.
If the input at B is 0, the
output is always 0.
24
LOWPASS
FILTER
Output the input at A as
the B filter gains time
constant, B x US.2.
In the above formula, set
the time when the output
of A reaches 63.3% C
stands for the filter
operation. If it is 0, the
operation is started.
25
PI_
CONTRL
P, I gain = A, B parameter
input, then output as C.
Conditions for
PI_PROCESS output:
C = 0: Const PI,
C = 1: PI_PROCESS-B
>= PI_PROCESS-OUT
>= 0,
C = 2: PI_PROCESS-B
>= PI_PROCESS-OUT
>= -(PI_PROCESS-B),
P gain = A/100, I gain =
1/(Bx Loop Time),
If there is an error with PI
settings, output is -1.
