
When the actual output frequency
d
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. frequency by V/f curve.

The wake up frequency must be higher than sleep frequency.
