Description
Activates/deactivates process PID control.
Note: Process PID control is only available in external
control; see section Local control vs. external control
20).
Process PID control inactive.
Process PID control active.
Process PID control is active when the drive is running.
Selects the first source of process feedback. See the control
chain diagram on page 403.
None.

Source selection (see Terms and abbreviations
Selects the second source of process feedback.
For the selections, see parameter
source.
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.
