Source selection (see Terms and abbreviations
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
selection.
The trim function is active. The trimming factor is relative to
the reference selected by parameter

The trim function is active. The trimming factor is a
combination of both Direct
proportions of each are defined by parameter
mix.
Selects whether trimming is used for correcting the speed,
torque or frequency reference.
Torque reference trimming.
Speed reference trimming.
Frequency reference trimming.
Selects the signal source for the trim reference.

Defines a multiplier for the trimming factor. This value is
multiplied by the result of parameter
