NOTE
• When inputting an analog signal to the terminal 1, give a positive voltage (0 to +10 V (+5 V)).
When a negative voltage (0 to -10 V (-5 V)) is input, the torque limit value set by the analog signal becomes "0".
• Functions of terminals 1 and 4 by control (— : no function)

*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 / CC-
Link IE TSN communication (Pr.810 = "2", Pr.805, Pr.806)
• When the CC-Link (FR-A8NC), CC-Link IE Field network (FR-A8NCE/FR-A800-GF), or CC-Link IE TSN (FR-A8NCG/FR-
A800-GN) 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 or CC-Link IE TSN is used, the torque limit value can be input using a remote register
(RWw2).
