:There is no reduced voltage. The rush current at the start of the inverter is increased but the motor reaction time is decreased.

:The effect of the reduced voltage is large.

The rush current is reduced but the motor reaction time is increased.

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.

(Set to or .)

Since jogging is a direct input operation and may be easily tripped, set the jogging frequency to 5 Hz or less.
