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, 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.
