Torque command / torque limit through CC-Link IE Field Network
communication (only for the FR-A800 series)
Torque commands can be given or the torque can be limited via CC-Link IE Field Network under Real sensorless vector
control, vector control, or PM sensorless vector control. The value is used to limit the torque during speed control or position
control, and to give a torque command during torque control. To limit the torque, set Pr.810 = "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.)

Can also be set from operation panel or parameter unit.
When a negative value is set as the torque limit, the torque is limited by the absolute value.
