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).

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%.
Reverse regeneration
• When the CC-Link communication (Ver. 2) is used in the quadruple or octuple setting (Pr.544="24, 28, or 128"), the torque
limit value can be input using a remote register (RWwC to RWwF) for each of the four quadrants.
Reverse regeneration
NOTE
• If "2" is set in Pr.810 while the communication option is not connected, a protective function (E.OPT) is activated (when the
PLC function is disabled).
• For the details of the FR-A8NC and the FR-A8NCE, refer to the Instruction Manual of each option.
