Code and
Features
Description
AP.37 PID Sleep
DT,
AP.38 PID Sleep
Freq
If an operation frequency lower than the value set at AP.38 is
maintained for the time set at AP.37, the operation stops and the PID
operation sleep mode starts.
AP.39 PID
WakeUp Lev,
AP.40 PID
WakeUp Mod
Starts the PID operation when in PID operation sleep mode. If AP.40 is
set to 0 (Below Level), the PID operation starts when the feedback
variable is less than the value set as the AP.39 parameter setting.
If AP.40 is set to 1 (Above Level), the operation starts when the
feedback variable is higher than the value set at AP.39. If AP.40 is set
to 2 (Beyond Level), the operation starts when the difference between
the reference value and the feedback variable is greater than the value
set at AP.39.
5.8.4 PID Switching (PID Openloop)
When one of the multi-function terminals (In.65
–69) is set to 23 (PID Openloop) and is
turned on, the PID operation stops and is switched to general operation. When the
terminal turns off, the PID operation starts again.
