Change The Control Method (Pr. 80, Pr. 81, Pr. 800) - Mitsubishi Electric FR-E700 Series Instruction Manual

Parameter
6.2.1

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

Set when selecting the control method for advanced magnetic flux vector control and general-pur-
pose magnetic flux vector control. The initial value is V/F control.
● Select a control mode using Pr. 800 "Control method selection".

Control method selection
Set a value other than "9999" in Pr. 80 and Pr. 81.
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".
Selection of control method
Select the inverter control method for V/F control, advanced magnetic flux vector control, and gen-
eral-purpose magnetic flux vector control.
(Pr. 80, Pr. 81 initial value)
Tab. 6-2:
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".
