Derivative time 1
50 seconds
• Sets derivative time 1 for OUT1.
Setting the value to 0 disables this function.
• Setting range: 0 to 1800 seconds
ARW 1
50%
• Sets ARW 1 (anti-reset windup 1) for OUT1.
• Setting range: 0 to 100%
Manual reset 1
0.0
• Sets reset value 1 manually.
• Setting range: 1000.0
DC voltage, current inputs: The placement of the decimal point
follows the selection.
OUT1 rate-of-change 1
0 %/second
• Sets OUT1 rate-of-change 1 (changing value of OUT1 MV for
1 second).
Setting the value to 0 disables this function.
See [OUT1 rate-of-change] below.
• Setting range: 0 to 100 %/second
If PID zone function “Used” is selected in [PID zone function], one zone
contains data from “PID zone value 1” to “OUT1 rate-of- change 1”.
Up to 5 zones can be set repeatedly.
OUT1 rate-of-change 5
0 %/second
• Sets OUT1 rate-of-change 5 (changing value of OUT1 MV for
1 second).
Setting the value to 0 disables this function.
See [OUT1 rate-of-change] below.
• Setting range: 0 to 100 %/second
[OUT1 rate-of-change]
For Heating control, if PV is lower than SV, output is generally turned from OFF to ON
as shown in (Fig. 7.2.3-1). If OUT1 rate-of-change is set, the output can be changed by
the rate-of-change (Fig. 7.2.3-2).
This control is suitable for high temperature heaters (which are made from molybdenum,
tungsten or platinum, etc., and used at approx. 1500 to 1800 ) which are easily burnt
out from turning on electricity rapidly.
