6.3.3 General-purpose magnetic flux vector control
(Pr. 71, Pr. 80, Pr. 81, Pr. 800)
General-purpose magnetic flux vector control is the same function as the FR-E500 series. Select this
control when the same operation characteristic is necessary. For other cases, select advanced mag-
netic flux vector control.
The above parameters can be set when Pr. 160 "User group read selection" = 0.
햲
Set a value other than "9999" in Pr. 80 and Pr. 81.
If the following conditions are not satisfied, select V/F control since malfunction such as insufficient
torque and uneven rotation may occur.
●
The motor capacity should be equal to or one rank lower than the inverter capacity.
●
Motor to be used is any of Mitsubishi standard motor, high efficiency motor (SF-JR, SF-HR 0.2 kW
or more) or Mitsubishi constant-torque motor (SF-JRCA four-pole, SF-HRCA 0.2 kW to 15 kW).
When using a motor other than the above (other manufacturer's motor), perform offline auto
tuning without fail.
●
Single-motor operation (one motor run by one inverter) should be performed.
●
The wiring length from inverter to motor should be within 30 m. (Perform offline auto tuning in
the state where wiring work is performed when the wiring length exceeds 30 m.)
●
Permissible wiring length between inverter and motor differs according to the inverter capacity
and setting value of Pr. 72 "PWM frequency selection" (carrier frequency) (refer to page 3-13).
