Use Pr. 178 to Pr. 189 to assign the terminals used for the X18 and MC signal. (Refer to page 231 )

Valid when Pr. 450 

≠ "9999".

Advanced magnetic flux vector control can be selected by setting the capacity, number and type of motor to be
used in Pr. 80 and Pr. 81. 

What is Advanced magnetic flux vector control?

The low speed torque can be improved by providing voltage compensation to flow a motor current which meets
the load torque. Output frequency compensation (slip compensation) is made so that the motor actual speed
approximates a speed command value. Effective when load fluctuates drastically, etc.

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 0.4kW or higher)

• Motor to be used is either Mitsubishi standard motor (SF-JR 0.4kW or higher), Mitsubishi high efficiency motor

(SF-HR 0.4kW or higher) or Mitsubishi constant torque motor (SF-JRCA 4P, SF-HRCA 0.4kW to 55kW). When

using a motor other than the above (SF-TH, other manufacturer's motors, etc.), 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.)

• For 75K or higher, do not use an option sine wave filter (MT-BSL/BSC) between the inverter and motor.
