Torque command / torque limit by CC-Link communication

Torque commands can be given or the torque can be limited by CC-Link communication under Real sensorless vector control,
or PM sensorless vector control. The value is used to limit the torque during speed control, and to give a torque command
during torque control. To limit the torque, Pr.810 Torque limit input method selection ="2". The torque command / torque limit
setting method can be selected using Pr.804 Torque command source selection . (Torque control cannot be performed with
a PM motor.)
