40.51 Set 1 trim mode 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 .
Off
Off The trim function is inactive. 0
Direct 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.
1
Proportional The trim function is active. The trimming factor is relative to
the reference selected by parameter 40.53 Set 1 trimmed ref
pointer.
2
Combined The trim function is active. The trimming factor is a
combination of both Direct and Proportional modes; the
proportions of each are defined by parameter 40.54 Set 1 trim
mix.
3
40.52 Set 1 trim selection Selects whether trimming is used for correcting the speed,
torque or frequency reference.
Speed
Torque Torque reference trimming. 1
Speed Speed reference trimming. 2

40.53 Set 1 trimmed ref
pointer
Selects the signal source for the trim reference. Not selected

40.54 Set 1 trim mix When parameter 40.51 Set 1 trim mode is set to Combined,
defines the effect of direct and proportional trim sources in the
final trimming factor.
0.000 = 100% proportional
0.500 = 50% proportional, 50% direct
1.000 = 100% direct

0.000...1.000 Trim mix. 1 = 1
40.55 Set 1 trim adjust Defines a multiplier for the trimming factor. This value is
multiplied by the result of parameter 40.51 Set 1 trim mode.
Consequently, the result of the multiplication is used to
multiply the result of parameter 40.56 Set 1 trim adjust.
