Simple mode parameter list
If the following conditions are not satisfied, select V/f control since malfunction such as insuffi-
cient torque and uneven rotation may occurr.
● The motor capacity should be equal to or one rank lower than the inverter capacity.
● Motor to be used is either Mitsubishi standard motor, high efficiency motor (SF-JR, SF-HR
two-pole, four-pole, sixpole 0.4kW or more) or Mitsubishi constant-torque motor (SF-JRCA,
SF-HRCA four-pole 0.4kW to 55kW). When using a motor other than the above (other
manufacturer's motor), perform offline auto tuning without fail. (advanced magnetic flux
vector control)
When performing real sensorless vector control, offline auto tuning are necessary even when
Mitsubishi motor is used.
● 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 actual wiring work is performed when the wiring length exceeds 30m.)
NOTES Uneven rotation slightly increases as compared to the V/f control. (It is not suitable for
machines such as grinding machine and wrapping machine which requires less uneven
rotation at low speed.)
When terminal assignment is changed using Pr. 178 to Pr. 189 "Input terminal function
selection", other functions may be affected. Please make setting after confirming the func-
tion of each terminal.
When advanced magnetic flux vector control is performed with an output filter, output torque
may decrease. In addition, do not use a sine wave filter.
Do not perform real sensorless vector control with an output filter.
When you consider to use output filters, please contact your Mitsubishi sales representative.
