Criterias 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
Criterias 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)
The drive goes to sleep mode (that is, the drive stops) when the output frequency of the drive
is less than the sleep frequency limit for longer than the time that is set in this parameter.
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)
P3.13.5.4 SP1 WAKE-UP MODE (ID 1019)
With these parameters, you can set when the drive wakes up from the sleep mode.
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.)
