When the actual output frequency
≤
Pr.11-06 and the time exceeds the setting of Pr.11-05,
the AC motor drive will be in sleep mode.
When the actual frequency command > Pr.11-07 and the time exceeds the setting of Pr.11-05,
the AC motor drive will restart.
When the AC motor drive is in sleep mode, frequency command is still calculated by PID.
When frequency reaches wake up frequency, AC motor drive will accelerate from Pr.01-05 min.

The wake up frequency must be higher than sleep frequency.
