Setting method
Select the running mode. Set the running mode to be used.

Fuzzy most suitable acceleration
and deceleration mode
Initial value
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.

setting
Adjust reduced voltage start.
Initial value
NOTE: How to set
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.
