Parameters 239
Selects a source that switches between two different
predefined minimum torque limit sets.
0 = minimum torque limit defined by
and maximum
torque limit defined by
are active
1 = minimum torque limit selected by
and maximum
torque limit defined by
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
and
. 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).
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
WARNING!
In torque control mode (vector motor
control) only.
