Actual signals and parameters
220
4024 PID SLEEP DELAY Defines the delay for the sleep start function. See parameter 4023 PID
SLEEP LEVEL. When the motor speed falls below the sleep level, the
counter starts. When the motor speed exceeds the sleep level, the counter is
reset.
60
0.0…3600.0 s Sleep start delay 1 = 0.1 s
4025 WAKE-UP DEV Defines the wake-up deviation for the sleep function. The drive wakes up if
the process actual value deviation from the PID reference value exceeds the
set wake-up deviation (
4025 ) longer than the wake-up delay ( 4026 ). Wake-up
level depends on parameter 4005 ERROR VALUE INV settings.
If parameter 4005 is set 0:
Wake-up level = PID reference (4010) - Wake-up deviation (4025).
If parameter 4005 is set to 1:
Wake-up level = PID reference (4010) + Wake-up deviation (4025)
See also figures in parameter 4023 PID SLEEP LEVEL.
0
x…x Unit and range depend on the unit and scale defined by parameters 4026
WAKE-UP DELAY and 4007 UNIT SCALE.
4026 WAKE-UP DELAY Defines the wake-up delay for the sleep function. See parameter 4023 PID
SLEEP LEVEL.
0.5
0.00…60.00 s Wake-up delay 1 = 0.01 s
4027 PID 1 PARAM SET Defines the source from which the drive reads the signal that selects
between PID parameter set 1 and 2.
PID parameter set 1 is defined by parameters
4001 … 4026 .
PID parameter set 2 is defined by parameters 4101 … 4126 .
