
When Pr.868 ≠ "0", the other functions of terminal 1 (auxiliary input, override function, PID control) do not operate.

When Pr.858 ≠ "0", PID control and speed commands using terminal 4 do not operate even when the AU signal is ON.

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.

Valid when vector control compatible options are installed and vector control is selected.
