This negative value determines the most negative torque value that can be applied
to the motor. If the device attempts to apply a more negative torque than this
limit, the torque command is clamped to this value.

% Motor Rated
Maximum limit for the torque producing Iq Current Feedback signal magnitude.
When the Iq Current Feedback signal is greater than this value for the duration
specified by Overtorque Limit Time attribute, the result is an Overtorque Limit
exception. This feature lets the device generate an exception if there is a sudden
increase in load torque during operation. This condition could occur if a bearing
fails, a hard stop is reached, or there is some other mechanical failure.
