LPF
(Low pass
filter) with
enable
Value of analog input 1 is filtered through LPF
(time constant U04) when the digital input 1 is
“1”. When the digital input 1 is “0”, the analog
input 1 is directly output.
LPF maintains the previous output value.
Therefore, when the digital 1 input changes
from 0 to 1, the output will be the value with
the previous output value added as the initial
value of LPF.

4006
Rate limiter
with enable
Value of analog input 1 is limited with change
rate specified in functions 1 and 2 when the
digital input 1 is “1”. When the digital input 1
is “0”, the analog 1 input is directly output.
When setting the initial value, carry out an
operation with the initial value for input 1 and
0 applied to input 2. Then, reflect the result as
the initial value (= previous output value) with
1 applied to input 2.
During the initialization or when the CLC
terminal is ON, the previous output value is
cleared to 0.
