 Torque command / torque limit using the CC-Link IE Field Network Basic
Torque commands can be given or the torque can be limited by CC-Link IE Field Network Basic 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, set 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.)

*1 The torque limit value can also be set using the operation panel.
*2 When a negative value is set as the torque limit, the torque is limited by the absolute value.
