254 Parameters
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.
