Source selection (see
Activates 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
40.05 Process PID trim output act

The trim function is inactive.
The 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
The trim function is active. The trimming factor is
relative to the reference selected by parameter
Set 1 trimmed ref pointer
The trim function is active. The trimming factor is a
