Parameters 349
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
0.0 … 32767.0 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
40.41 Set 1 sleep mode Selects the mode of the sleep function.
See also section
Sleep function for process PID control (page
104 ).
Not selected
Not selected Sleep function disabled. 0
Internal The output of the PID controller is compared to the value of
40.43 Set 1 sleep level .
If the PID controller output remains below the sleep level
longer than the sleep delay (
40.44 Set 1 sleep delay ), the
drive enters sleep mode.
Parameters
40.44 … 40.48 are in force.
1
External The sleep function is activated by the source selected by

Parameters 40.44 … 40.46 and 40.48 are in force.
2
40.42 Set 1 sleep enable Defines a source that is used to activate the PID sleep
function when parameter
40.41 Set 1 sleep mode is set to
External .
