  When the absolute value of the torque reference input from the host controller or output by the speed regulator is larger than the absolute value of the torque reference limit, the actual torque reference of the servo drive is restricted to the torque reference limit. Otherwise, the torque reference input from the host controller or output by the speed regulator is used.

  Only one torque reference limit is valid at a moment. Both positive and negative torque limits does not exceed the maximum torques of the servo drive and motor and ±300.0% of the rated torque.
