Simple mode parameter list
Large starting torque and low speed torque are necessary
(Advance magnetic flux control, general-purpose magnetic flux vector
control) (Pr. 71, Pr. 80, Pr. 81, Pr. 800)
Advanced magnetic flux vector control can be selected by setting the capacity, poles and type
of the motor used in Pr. 80 and Pr. 81.
Advanced magnetic flux vector control, general-purpose magnetic flux vector control?
The low speed torque can be improved by providing voltage compensation so that the motor cur-
rent which meets the load torque to flow. Output frequency compensation (slip compensation)
is made so that the motor actual speed approximates a speed command value. Effective when
load fluctuates drastically, etc.
General-purpose magnetic flux vector control is the same function as it is for the FR-E500 se-
ries. Select this control when operation characteristics as similar as possible are required when
replacing from the FR-E500 series. For other cases, select advanced magnetic flux vector con-
Number of motor
Refer to appendix A for the rated inverter output current.
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. (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 (four-pole),
SF-HRCA 0.4kW to 15kW). When using a motor other than the above (other manufactu-
rer'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.)

Set the rated motor current.
By selecting a standard motor or constant-torque
motor, thermal characteristic and motor constants of
each motor are set.
Set the applied motor capacity.
Set the number of motor poles.
