Speed control under Real sensorless vector control, vector control, PM sensorless vector control
Torque limit level by communication options (Pr. 810 = "2", Pr. 805, Pr. 806)
● When a communication option (FR-A8NC or FR-A8NCE) is used, the Pr. 805 or Pr. 806 setting is
used as the torque limit value. (Internal torque limit 2)
● When the CC-Link communication (Ver. 2) is used in the quadruple or octuple setting (Pr. 544="14,
18, 114, or 118"), the torque limit value can be input using a remote register (RWwC).
● When the CC-Link IE Field Network is used, the torque limit value can be input using a remote
register (RWw2).

Tab. 5-30:
The torque limit setting is defined as an absolute value.
Can also be set from operation panel or parameter unit.
The torque can also be limited by setting a value in Pr. 805 or Pr. 806.
Setting range if set by operation panel or parameter unit is "673 to 1327 (-327% to 327%)"; setting
increment is 1%.
