Changing The Control Method (Pr. 80, Pr. 81, Pr. 800) - Mitsubishi Electric 700 Series Instruction Manual

5.3.1

Changing the control method (Pr. 80, Pr. 81, Pr. 800)

Set when selecting the control method for Advanced magnetic flux vector control and General-purpose magnetic flux
vector control. The initial value is V/F control.
Select a control mode using Pr. 800 Control method selection.

∗ Set a value other than "9999" in Pr. 80 and Pr. 81.
(1) Setting of the motor capacity and the number of motor poles (Pr. 80, Pr. 81)
Motor specifications (motor capacity and number of motor poles) must be set to select Advanced magnetic flux vector
control or General-purpose magnetic flux 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
Select the inverter control method for V/F control, Advanced magnetic flux vector control, and General-purpose magnetic
flux vector control.
