Description
The trim function is active. The trimming factor is a
combination of both Direct
the proportions of each are defined by parameter
Set 1 trim 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.
None.

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
Trim mix.
Defines a multiplier for the trimming factor. This value
is multiplied by the result of parameter
mode.
Consequently, the result of the multiplication is used
to multiply the result of parameter
source.
Multiplier for trimming factor.
Selects the reference to be trimmed.
