Description
Defines how process feedback is calculated from the two
feedback sources selected by parameters
feedback 1 source and 40.09 Set 1 feedback 2
Source 1.
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 the unit for parameters 40.01...40.05,
and 40.47.

User-definable unit 1. The name of the unit can be edited on
the control panel by choosing Menu – Settings – Edit texts.
Defines, together with parameter
a general scaling factor for the process 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
nominal motor speed at 50 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
40.15. For example, the values 50 and 1500 would produce
the same scaling as 1 and 30.
Process setpoint base.
See parameter 40.14 Set 1 setpoint
Process PID controller output base.
Selects the first source of process PID setpoint. This setpoint
is available in parameter
setpoint 1. See the control chain diagram on page 658.
