4) PID Sleep Mode(Sleep)
APP-37 PID Sleep DT, APP-38 PID Sleep Freq : If the inverter continues to operate for the time set in APP-37 PID Sleep
DT under the frequency set in APP-38 Sleep Freq, is stops operating and goes into Sleep Mode. For the threshold of shift
from PID Sleep Mode to PID operation mode back, see APP-39 PID WakeUp Lev.
APP-39 PID WakeUp Lev, APP-40 PID WakeUp Mod : Sets the threshold of starting PID operation from the PID sleep
mode described above. If you select 0(Below Level) in APP-40 and the feedback is smaller than set in APP-39 PID
WakeUp Lev, PID operation resumes. No. 1(Above Level) restarts operation when it is larger than the value set in APP-39.
No. 2(Beyond Level) restarts operation when the difference between the reference and feedback is larger than the value
set in APP-39.
5) PID Operation by pass (PID Openloop)
If, among multi-function terminal blocks, the terminal set at No. 22 PID Openloop in IN-65~75 Px Define is input, PID
operation stops and changes to normal operation. The terminal OFF, PID operation resumes.
