Parameters 267
40.35
Set 1 derivation filter
time
Defines the time constant of the 1-pole filter used to
smooth the derivative component of the process PID
controller.
0.0 s
0.0…10.0 s
Filter time constant.
10 = 1 s
40.36
Set 1 output min
Defines the minimum limit for the process PID controller
output. Using the minimum and maximum limits, it is
possible to restrict the operation range.
0.00
-200000.00…
200000.00
Minimum limit for process PID controller output.
1 = 1
40.37
Set 1 output max
Defines the maximum limit for the process PID controller
output. See parameter
40.36
Set 1 output min
.
100.00
-200000.00…
200000.00
Maximum limit for process PID controller output.
1 = 1
40.38
Set 1 output freeze
enable
Freezes (or defines a source that can be used to freeze)
the output of the process PID controller, keeping the
output at the value it was before freeze was enabled. This
feature can be used when, for example, a sensor
providing process feedback must to be serviced without
stopping the process.
1 = Process PID controller output frozen

Not selected
Not selected
Process PID controller output not frozen.
0
Selected
Process PID controller output frozen.
