YASKAWA Sigma-7 SGD7S Series - 7.8.2 Internal Torque Limits

If you set a value that exceeds the maximum torque of the Servomotor,
the torque will be limited to the maximum torque of the Servomotor.
7.8.2 Internal Torque Limits
If you use internal torque limits, the maximum output torque will always be limited to the
specified Forward Torque Limit (Pn402) and Reverse Torque Limit (Pn403).
