Torque command / torque limit through CC-Link IE TSN
communication (only for the FR-A800 series)
Torque commands can be given or the torque can be limited via CC-Link IE TSN 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.
