266 Parameters
30.18 Minimum torque sel 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
592 .
