Minimum torque 1 /
uint32 Selects a source that switches between two different
predefined minimum torque limits.
0 = Minimum torque limit defined by
30.19 is active
1 = Minimum torque limit selected by 30.21 is active
The user can define two sets of torque limits, and
switch between the sets using a binary source such as
a digital input.
The minimum limit selection (
30.18 ) is independent of
the maximum limit selection ( 30.25 ).
The first set of limits is defined by parameters 30.19
and 30.20 . The second set has selector parameters for
both the minimum ( 30.21 ) and maximum ( 30.22 ) limits
that allows the use of a selectable analog source (such
as an analog input).

The limit selection parameters are updated on a 10 ms
time level.
Note: In addition to the user-defined limits, torque may
be limited for other reasons (such as power limitation).
