4.3.2 Change the control method (Pr. 80, Pr. 81, Pr. 451, Pr. 800)
(1) Setting of the motor capacity and the number of motor poles (Pr. 80, Pr. 81 )
⋅ Motor specifications(the motor capacity and the number of motor poles) must be set to select Advanced magnetic
flux vector control, Real sensorless vector control or vector control.
⋅ Set the motor capacity (kW) in Pr. 80 Motor capacity and set the number of motor poles in Pr. 81 Number of motor
poles.
(2) Selection of control method and control mode
⋅ Select the inverter control method for V/F control, Advanced magnetic flux vector control (speed control), Real
sensorless vector control (speed control, torque control) and vector control (speed control, torque control, and
position control).
*1 If FR-A7AP/FR-A7AL is not installed, the control method is Advanced magnetic flux vector control.
*2 Control method is V/F control regardless of the setting value of Pr. 800 when "9999" is set in Pr. 80 Motor capacity or Pr. 81 Number of motor poles.
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 position 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).
