Mitsubishi Electric FR-A820-00046 Instruction Manual page 961

Parameters
Torque command / torque limit through CC-Link IE Field Network communication
● 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.)
● For setting the torque limit parameters, refer to page 5-90. For setting the torque command
parameters, refer to page 5-138.
● 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.

● Relationship between the Pr. 804 setting, the setting range, and the actual torque command /
torque limit (when setting is made from CC-Link IE Field Network communication)
Pr. 804 setting
1, 3
5, 6
Tab. 5-352: Setting range depending on Pr. 804 settings
The torque limit setting is defined as an absolute value.
● Torque command / torque limit setting method
Writing in RWw2:
Set the torque command / torque limit value in RWw2.
Set "1" in RY23 (or RY24).
Writing in Pr. 805 or Pr. 806:
Set link parameter extended setting = H08 for RWw10 (12, 14, 16, 18, 1A).
Set instruction codes H85 or H86
Set the torque command / torque limit value in RWw11 (13, 15, 17, 19, 1B).
Set "1" in RY25.
