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).
