PARAMETERS
• Functions of terminals 1 and 4 by control (: no function)
 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 FR-A8AP (option) is installed and vector control is selected.
Second torque limit level (TL signal, Pr.815)
•For Pr.815 Torque limit level 2, when the Torque limit selection (TL) signal is ON, the setting value of Pr.815 is the limit
value regardless of the setting of Pr.810 Torque limit input method selection.
• To assign the TL signal, set "27" in any of Pr.178 to Pr.189 (input terminal function selection).
NOTE
• Changing the terminal assignment using Pr.178 to Pr.189 (input terminal function selection) may affect the other
functions. Set parameters after confirming the function of each terminal.
