 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%.
• 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.
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.
