Function 1, Function 2
(U04, U05, etc.)
4006
Rate limiter
with enable
When input 2 (digital input) is 0,
input 1 (analog input) is output
as is. When input 2 is 1, the
input 1 change is restricted with
the rate of change specified
with function 1 and 2.
The initial value is the input 1
value when input 2 changes
from 0 to 1.
When terminal [CLC] is ON, the
previous output value is
cleared to zero.

rate
limiter
Function 1: Rise rate of
change
Time taken to change by
100%
0: No restriction
0.01 to 600 s
Function 2: Fall rate of
change
Time taken to change by
100%
0: Same rate of change
as function 1
0.01 to 600 s

Selector 3
When the step output signal
(SOXX) specified with function
1 is 0, input 1 (analog input) is
output as is. When the step
output signal specified with
function 1 is 1, input 2 (analog
input) is output as is.

Function 1: Step number
Function 2: Not required
The setting after the
decimal point is ignored.

Selector 4
When input 2 (digital input) is 0,
input 1 is output as is. When
input 2 is 1, step output signal
set with function 1 is output.

Reading
function
codes
The function code is specified
with function 1 and 2, and
function code data is output.
The function code type is
specified with function 1, and
the last two digits of the
function code are specified with
function 2.
The format in which data is
read correctly is shown below.
(However, values are restricted
to the -9990 to 9990 range.)
Furthermore, [29] expresses
20000 as 100%.)
[1], [2], [3], [4], [5], [6], [7], [8],
[9], [10], [12], [22], [24], [29],
[35], [37], [45], [61], [67], [68],
[74], [92], [93]
Data formats other than the
above cannot be read correctly.
Do not use any other format.
Output
Input 1
Input 2
U04 U05
[U121]
READ
Function 1: Function
code type 0 to 255
Function 2: Function
code number 0 to 99
The setting after the
decimal point is ignored.
Refer to “■Configuration
of function codes” on P5-
405 for details on the
function code type. For
details on data format
numbers, refer to the
Communication User’s
Manual (24A7-E-xxxx).
