11 - 05 Sleep/Wake Up Detection Time Unit: 0.1
Settings 0.0 to 6550.0 sec Factory Setting: 0.0
11 - 06 Sleep Frequency Unit: 0.01
Settings 0.00 to Fmax Hz Factory Setting: 0.00
11 - 07 Wakeup Frequency Unit: 0.01
Settings 0.00 to Fmax Hz Factory Setting: 0.00
 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.
