Feedback lost detecting value: This value corresponds to the full range (100%),
and the system always keep on monitoring the PID feedback value. As the
feedback value is less or equal to the feedback lost detecting value, a timing
process is trigged to start. If the timing is exceeds the feedback lost detecting time,
the system will display an alarm code indicating PID feedback lost.

As PID sleep is selected, VFD keeps on monitoring the feedback and compares it
to the PID setting. If feedback is higher than setting, VFD will start sleep detecting.
Then after PID sleep detecting delay time and if the feedback is still higher than
setting, VFD will decrease output frequency gradually until Lower retaining
frequency of PID sleep detecting, and keep PID Lower retaining frequency running
time at this retaining frequency. If the feedback is still higher than the setting, VFD
will decrease output frequency to 0Hz and enter sleeping mode. During the above
process, if the feedback is lower than the setting, sleep detecting will be fail and
VFD returns to PID control mode. While in sleeping mode, if the feedback is lower
