NOTE: When the fuzzy most suitable acceleration and deceleration are selected and the load inertia (motor shaft
conversion) is more than about 20 times of that of the individual motor, an overvoltage trip may occur.
If this occurs, reset the mode to the normal running mode. For other precautions, refer to "Precautions for
fuzzy most suitable acceleration and deceleration" of Appendix 1.
Set the running command so as to be inputted to the terminal.
