Change The Control Method (Pr. 80, Pr. 81, Pr. 451, Pr. 800) - Mitsubishi Electric FR-A700 Instruction Manual

Control mode
6.2.2

Change the control method (Pr. 80, Pr. 81, Pr. 451, Pr. 800)

Set when selecting the advanced magnetic flux vector control, real sensorless vector control or
vector control. Select a control mode from speed control mode, torque control mode and posi-
tion control mode under real sensorless vector control or vector control. The initial value is V/f
control.
● Select a control method using Pr. 800 (Pr. 451) "Control method selection".
● Each control method can be switched using a method switching signal (MC).
