When the Pr. 868 setting is other than "0", other functions of terminal 1 (auxiliary input, override function, PID control) do not function.
*2
When the Pr. 858 setting is other than "0", PID control and speed command from terminal 4 do not function even if the AU signal turns ON.
*3
When "1" (magnetic flux command) or "4" (torque limit) is set in both Pr. 858 and Pr. 868, function of terminal 1 has higher priority and terminal 4
has no function.

Setting is valid only when exercising vector control with the FR-A7AP/FR-A7AL (option).
