 If PID frequency is less than the sleep frequency when the drive starts running, the drive will
be in sleep mode immediately and won’t limit by this parameter.
 Related parameters: Pr.10.15(Sleep Frequency) and Pr.10.16(Wakeup Frequency)
10.15 Sleep Frequency Unit: 0.01
Settings 0.00 to 600.0 Hz Factory Setting: 0.00
 This parameter set the frequency for the AC motor drive to be in sleep mode.
 The AC motor drive will stop outputting after being sleep mode, but PID controller keep
operating.
10.16 Wakeup Frequency Unit: 0.01
Settings 0.00 to 600.0 Hz Factory Setting: 0.00
 This parameter is used to set the wakeup frequency to restart the AC motor drive after sleep
mode.
 The wake up frequency must be higher than sleep frequency.
 When the actual output frequency
≤
Pr.10.15 and the time exceeds the setting of Pr.10.14,
the AC motor drive will be in sleep mode and the motor will decelerate to stop by
Pr.01.10/01.12 setting.
 When the actual frequency command > Pr.10.16 and the time exceeds the setting of Pr.10.14,
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
minimum frequency following the V/f curve.
