(N) Operation via communication and its settings
Torque command / torque limit through CC-Link IE TSN communication
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.
 RWw2 function according to the parameter settings and the control mode
Set the torque command value or the torque limit value in RWw2. The RWw2 function is switched according to the Pr.804
and Pr.810 settings and the control mode.

Setting method
1. Set the torque command / torque limit value in RWw2.
Writing in RWw2
2. Set "1" in RY23 (or RY24).
1. Set link parameter extended setting = H08 for RWw10 (12, 14, 16, 18, 1A).
Writing in Pr.805 or 2. Set instruction codes H85 or H86
Pr.806 3. Set the torque command / torque limit value in RWw11 (13, 15, 17, 19, 1B).
4. Set "1" in RY25.
