Parameters 223
40.39 Set 1 deadband
range Defines a deadband around the setpoint. Whenever process
feedback enters the deadband, a delay timer starts. If the
feedback remains within the deadband longer than the delay
(
40.40 Set 1 deadband delay ), the PID controller output is
frozen. Normal operation resumes after the feedback value
leaves the deadband.
0.0
0……200000.0 Deadband range. 1 = 1
40.40 Set 1 deadband
delay Delay for the deadband. See parameter 40.39 Set 1
deadband range .
0.0 s
0.0 … 3600.0 s Delay for deadband area. 1 = 1 s
40.43 Set 1 sleep level Defines the start limit for the sleep function. If the value is 0.0,
set 1 sleep mode is disabled.
The sleep function compares PID output (parameter
40.01
Process PID output actual ) to the value of this parameter. If
PID output remains below this value longer than the sleep
delay defined by
40.44 Set 1 sleep delay , the drive enters the
sleep mode and stops the motor.
0.0
0.0…200000.0 Sleep start level. 1 = 1
40.44 Set 1 sleep delay Defines a delay before the sleep function actually becomes
enabled, to prevent nuisance sleeping.
The delay timer starts when the sleep mode is enabled by
parameter
40.43 Set 1 sleep level , and resets when the sleep
mode is disabled.
60.0 s
0.0…3600.0 s Sleep start delay. 1 = 1 s
40.45 Set 1 sleep boost
time Defines a boost time for the sleep boost step. See parameter
40.46 Set 1 sleep boost step .
0.0 s
0.0…3600.0 s Sleep boost time. 1 = 1 s
40.46 Set 1 sleep boost
step When the drive is entering sleep mode, the process setpoint
is increased by this value for the time defined by parameter
40.45 Set 1 sleep boost time .
If active, sleep boost is aborted when the drive wakes up.
