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 641.
Set 1 trim mode40.51
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 Set 1 trimmed
ref pointer.
Proportional
3The 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.
Combined
Torque / uint16Selects whether trimming is used for correcting the speed,
torque or frequency reference.
