General-Purpose Magnetic Flux Vector Control (Pr. 71, Pr. 80, Pr. 81, Pr. 800) - Mitsubishi Electric FR-E720-600 Instruction Manual

Adjust the output torque of the motor (current)
4.4.3

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 79)

The above parameters can be set when
∗ 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 more)
Motor to be used is any of Mitsubishi standard motor, high efficiency motor (SF-JR, SF-HR 0.2kW or more) or
Mitsubishi constant torque motor (SF-JRCA, SF-HRCA four-pole 0.4kW 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 (98.42feet). (Perform offline auto tuning in the
state where wiring work is performed when the wiring length exceeds 30m (98.42feet).)
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.
