10.14.5 SLEEP FUNCTION
P3.13.5.1 SP1 SLEEP FREQUENCY (ID 1016)
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 value of this parameter is used when the signal of the PID controller setpoint is taken
from the setpoint source 1.
Criteria for going to sleep mode
•
Output frequency remains below sleep frequency for longer than defined sleep delay
time
•
PID feedback signal remains above defined wake up level
Criteria for waking from sleep
•
PID feedback signal falls below defined wake up level
NOTE!
A wrong set wake up level might not allow the drive to go into sleep mode
P3.13.5.2 SP1 SLEEP DELAY (ID 1017)
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.
The value of this parameter is used when the signal of the PID controller setpoint is taken
from the setpoint source 1.
P3.13.5.3 SP1 WAKE-UP LEVEL (ID 1018)
Use this parameter to set the level at which the drive wakes up from the sleep state.
When the PID feedback value goes below the level that is set with this parameter, drive
wakes up from the sleep state. The operation of this parameter is selected with wake up
mode parameter.
P3.13.5.4 SP1 WAKE-UP MODE (ID 1019)
Use this parameter to select the operation for the wake up level parameter.
The drive wakes up from the sleep mode when the value of PID Feedback goes below the
Wake-up level.
This parameter defines if Wake-up level is used as a static absolute level or as a relative
level which follows PID setpoint value.
Selection 0 = Absolute level (The wake-up level is a static level that does not follow the
setpoint value.)
Selection 1 = Relative setpoint (The wake-up level is an offset below the actual setpoint
value. The wake-up level follows the actual setpoint.)
