Minimum limit for the torque producing Iq Current Feedback signal magnitude.
When the Iq Current Feedback is less than this value for the duration specified by
Undertorque Limit Time attribute, the result is an Undertorque Limit exception.
This feature lets the device generate an exception if there is a sudden decrease in
load torque during operation. This condition could occur, for example, if a load
coupling breaks or a tensioned web material breaks.
