Not selected / uint32Activates (or selects a source that activates) tracking
mode. In tracking mode, the value selected by
parameter 40.50 Set 1 tracking ref selection is
substituted for the PID controller output. See also

Off / uint16Activates the trim function and selects between direct
and proportional trimming (or a combination of both).
With trimming, it is possible to apply a corrective factor
to the drive reference (setpoint). The output after
trimming is available as parameter 40.5 Process PID
trim output act.
See the control chain diagram on page 759.

0The trim function is inactive.Off
1The trim function is active. The trimming factor is
relative to the maximum speed, torque or frequency;
the selection between these is made by parameter
40.52 Set 1 trim selection.
Direct
2The trim function is active. The trimming factor is
relative to the reference selected by parameter 40.53
