1016 SLEEP FREQUENCY 57 (2.1.15)
The drive goes to sleep mode (that is, the drive stops) when the output frequency of the drive
is less than the frequency limit that is set in this parameter for a time greater than that
determined by parameter ID1017. During the Stop state, the PID controller is operating
switching the AC drive to Run state when the actual value signal either falls below or exceeds
(see parameter ID1019) the Wake-up level determined by parameter ID1018. See Fig. 81 AC
drive sleep function.
1017 SLEEP DELAY 57 (2.1.16)
The minimum quantity of time during which the frequency has to stay below the sleep level
before the drive stops. See Fig. 81 AC drive sleep function.
1018 WAKE-UP LEVEL 57 (2.1.17)
The wake-up level defines the level below which the actual value must fall or which has to be
exceeded before the Run state of the AC drive is restored.
