Description
Sum of sources 1 and 2.
Source 2 subtracted from source 1.
Source 1 multiplied by source 2.
Source 1 divided by source 2.
Smaller of the two sources.
Greater of the two sources.
Average of the two sources.
Square root of source 1.
Square root of (source 1 - source 2).
Square root of (source 1 + source 2).
Square root of source 1 + square root of source 2.
Defines the filter time constant for process feedback.
Feedback filter time.
Defines, together with parameter
scaling, a general scaling factor for the external PID
control chain. The scaling can be utilized when, for
example, the process setpoint is input in Hz, and the
output of the PID controller is used as an rpm value in
speed control. In this case, this parameter might be set to
50, and parameter 40.15
Hz.
In effect, the output of the PID controller [40.15] when
deviation (setpoint - feedback) = [40.14] and [40.32] = 1.
Note: The scaling is based on the ratio between
and 40.15. For example, the values 50 and 1500 would
produce the same scaling as 1 and 3.
