This is the second one of PID sleep mode, and it differs in the following two conditions (as showed in figure F8-6):
1
)
if feedback value is smaller than reference and larger than reference * (1 - set deviation
【
F8.14
】
), and output
frequency change rate is within 6%, the sleep mode is entered after delay time
【
F8.17
】
.
2
)
if feedback value increases to above reference value, the sleep mode is entered after delay time
【
F8.17
】
; otherwise,
if the feedback value decreases to under wake-up threshold
【
F8.16
】
, it will wake up immediately.

F8.15 defines the feedback value when the driver is entering sleep mode. If the actual feedback is larger than this set
value, and the output frequency arrives at lower limit, the driver will enter sleep mode (zero speed operation) after delay
time defined by F8.17.
F8.16 defines the feedback limit when the driver is entering operating state from sleep mode. When PID selects positive
characteristic and the the actual feedback is smaller than this set value (or when PID selects negative characteristic and
