Parameters 223
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
(
), 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
Delay for the deadband. See parameter
0.0 s
0.0 … 3600.0 s
Delay for deadband area.
1 = 1 s
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
) to the value of this parameter. If
PID output remains below this value longer than the sleep
delay defined by
, the drive enters the
sleep mode and stops the motor.
0.0
0.0…200000.0
Sleep start level.
1 = 1
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
, and resets when the sleep
mode is disabled.
60.0 s
0.0…3600.0 s
Sleep start delay.
1 = 1 s
Defines a boost time for the sleep boost step. See parameter
.
0.0 s
0.0…3600.0 s
Sleep boost time.
1 = 1 s
When the drive is entering sleep mode, the process setpoint
is increased by this value for the time defined by parameter
.
If active, sleep boost is aborted when the drive wakes up.
0.0 PID

0.0…200000.0 PID
