Speed control by Real sensorless vector
control, vector control
Terminal 1, 4 function according to control (⎯ : without function)
*1 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.
*4 Setting is valid only when exercising vector control with the FR-A7AP/FR-A7AL (option).

⋅ For Pr. 815 Torque limit level 2 , the Pr. 815 value is a torque
limit value regardless of Pr. 810 Torque limit input method
selection when the torque limit selection signal (TL) is ON.
⋅ Set "27" in Pr. 178 to Pr. 189 (input terminal function selection)
to assign a function to the TL signal.
CAUTION
⋅ 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.
