*1 When Pr.868 ≠ "0", the other functions of terminal 1 (auxiliary input, override function, PID control) do not operate.
*2 When Pr.858 ≠ "0", PID control and speed commands using terminal 4 do not operate even when the AU signal is ON.
*3 When both Pr.858 and Pr.868 are "1" (magnetic flux command) or "4" (torque limit), the function of terminal 1 has higher priority, and terminal 4
does not function.
*4 Valid when Vector control compatible options are installed and the Vector control is selected.
 Torque limit level through the CC-Link/CC-Link IE Field Network
communication (Pr.810 = "2", Pr.805, Pr.806)
• When the CC-Link (FR-A8NC) or CC-Link IE Field network (FR-A8NCE/FR-A800-GF) communication 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).

*1 The torque limit setting is defined as an absolute value.
*2 Can also be set from operation panel or parameter unit.
*3 The torque can also be limited by setting a value in Pr.805 or Pr.806.
*4 If set by operation panel or parameter unit, setting range is "673 to 1327 (-327% to 327%)", setting increment is 1%.
