Functions and
Operations
Set "P" (proportional band) of PID set 3 to 50.00 %FS.
1. Press the L key repeatedly to move to "PID setting level" (Display 3 shows
l.pid).
2. Use the UD keys to set "Display PID selection" to "3".
3. Press the M key to select "P (Proportional band)". To check the bank
number, view the leading digit of the setting data.
4. Use the UD keys to set the value to "50.00".
• A PID Set No. (1 to 8) is set in "PID Set No." in "Bank setting level".
For this reason, PID control parameters different from the selected
bank can be used during operation.
• If "PID Set No." is set to "0", the PID set is automatically selected
(PID auto selection) according to previously set conditions.
● PID set automatic
selection
When "PID Set No." is set to "0" in a bank, the PID set is automatically
selected according to previously set conditions.
In the example at left ("PID set selection data" is set to "PV"),
When PV
≤ 200.0°C, PID Set 1 is used
When 200.0 < PV
≤ 400.0°C, PID Set 2 is used
"PID automatic selection range upper limit" is set so that the value
increases as the PID Set No. increases.
However, note that the value for PID Set 8 is internally fixed at
"Automatic selection range upper limit" = 999.9% FS.
To prevent chattering when changing PID sets, hysteresis can be set
in "PID set selection hysteresis".
PV or DV (deviation) can be selected for the "PID set selection data".
