Mitsubishi Electric 800 Series Instruction Manual page 139

Control method
Setting 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.
NOTE
• Setting the number of motor poles in Pr.81 changes the Pr.144 Speed setting switchover setting automatically. (Refer to
page 345.)
Selection of control method and control mode
• Select the inverter control method from V/F control, Advanced magnetic flux vector control (speed control), Real sensorless
vector control (speed control, torque control), vector control (speed control, torque control, and position control), and PM
sensorless vector control (speed control, position control).


The setting values of 100 and above are used when the fast-response operation is selected.

Advanced magnetic flux vector control if a vector control compatible option is not installed.

The operation for the setting of "20 or 110" is performed when a value other than "9 or 109" is set.

The operation for the setting of "20 or 110" is performed when a value other than "9999" is set.

V/F control when Pr.80 or Pr.81 is "9999", regardless of the Pr.800 setting.
