30.18 Torq lim sel Selects a source that switches between two different
predefined minimum torque limit sets.
0 = minimum torque limit defined by 30.19 and maximum
torque limit defined by 30.20 are active
1 = minimum torque limit selected by 30.21 and maximum
torque limit defined by 30.22 are 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 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).
Note: In addition to the user-defined limits, torque may be
limited for other reasons (such as power limitation). See block
diagram Torque limitation on page 496.
