Parameters 197
Selects a source that switches between two different
predefined minimum torque limits.
0 = Minimum torque limit defined by
is active
1 = Minimum torque limit selected by
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 (
) is independent of the
maximum limit selection (
).
The first set of limits is defined by parameters
. The second set has selector parameters for both the
minimum (
) and maximum (
) 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
.
