Adjustment of the output torque (current) of the motor
5.4.3 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 magnetic
flux vector control. (Refer to page 95)

The above parameters can be set when Pr. 160 User group read selection = "0".(Refer to page 167)
∗ Set a value other than "9999" in Pr. 80 and Pr. 81 .
POINT
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. (note that the capacity
should be 0.1kW or higher)
Motor to be used is any of Mitsubishi standard motor (SF-JR 0.2kW or higher), high efficiency motor (SF-JR,
SF-HR 0.2kW or higher) or Mitsubishi constant-torque motor (SF-JRCA four-pole, SF-HRCA 0.2kW to 15kW).
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 30m. (Perform offline auto tuning in the state where
wiring work is performed when the wiring length exceeds 30m.)
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 19 for the permissible wiring length.
