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.

When output frequency
≦
sleep frequency and time > detection time, it will go into sleep mode.
When min. output frequency
≦
PID frequency
≦
lower bound of frequency and sleep function
is enabled (output frequency
≦
sleep frequency and time > detection time), frequency will be 0
(in sleep mode). If sleep function is disabled, frequency command = lower bound frequency.
When PID frequency < min. output frequency and sleep function is enabled (output frequency
≦
sleep frequency and time > detection time), output frequency =0 (in sleep mode).
If output frequency
≦
sleep frequency but time < detection time, frequency command = lower
frequency. If sleep function is disabled, output frequency =0.
