Control method Parameters
5 - 56
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 se-
lecting Advanced magnetic flux vector control, Real sensorless vector control, Vector control, and PM
sensorless vector control. Select a control mode from speed control mode, torque control mode and
position control mode under Real sensorless vector control or vector control. The initial setting is V/
F control.
When using an IPM motor MM-CF, simply performing the IPM parameter initialization enables the PM
sensorless vector control and selects the speed control and position control.
●
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).
