5.2.2
Changing the control method
Set the control method and control mode.
V/F control, Advanced magnetic flux vector control, Real sensorless vector control, Vector control, and PM sensorless
vector control are the control methods available for selection.
The control modes are speed control, torque control, and position control.
These are set when selecting Advanced magnetic flux vector control, Real sensorless vector control, Vector control,
and PM sensorless vector control. Under Real sensorless vector control, select a control mode from the speed control
and torque control modes. Under Vector control, select a control mode from the speed control, torque control, and
position control modes.
• Select a control method and control mode by using Pr.800 (Pr.451) Control method selection.
• The control mode can be switched using the mode switching signal (MC).
