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). Refer
to the block diagram on page 634.
