1016 SLEEP FREQUENCY 57 (2.1.15)
Use this parameter to set the limit below which the output frequency of the drive must stay
for a set time before the drive goes to the sleep state.
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)
Use this parameter to set the minimum duration that the output frequency of the drive must
stay below the set limit before the drive goes to the sleep state.
See Fig. 81 AC drive sleep function.
1018 WAKE-UP LEVEL 57 (2.1.17)
Use this parameter to set the level at which the drive wakes up from the sleep state.
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.
