Code and Features
Description
AP.37 PID Sleep DT,
AP.38 PID Sleep
Freq
If an operating frequency lower than the value set in AP.38 is maintained for
the time set at AP.37, the operation stops and the inverter will enter sleep
mode.
AP.39 PID WakeUp
Lev,
AP.40 PID WakeUp
Mod
When in Sleep Mode, normal PID Control operation will resume when:
AP.40 -> 0 (Below Level): the feedback variable is less than the value set in
AP.39, PID WakeUp Lev setting.
AP.40 -> 1 (Above Level): the feedback variable is higher than the value set in
AP.39.
AP.40 -> 2 (Beyond Level): the difference between the reference value and
the feedback variable is greater than the value set at AP.39.
PID Switching (PID Openloop)
When one of the multi-function (digital) terminals (In.65~69) is set to 23 (PID Openloop) and is
activated, PID operation stops and is switched to general operation. When the terminal is de-
activated, the PID operation resumes.
Note
When switching from PID operation to general operation, [%] values are converted to [Hz]
values. The normal PID output, PID OUT, is unipolar, and is limited by AP.29 (PID Limit Hi)
and AP.30 (PID Limit Lo). A 100.0% calculation of the PID OUT value is based on the dr.20
(MaxFreq) parameter setting.
