Parameters Speed control under Real sensorless vector control, vector control, PM sensorless vector control
FR-A800 5 - 89
●
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 vector control compatible options are installed and vector control is selected.
