☆ Setting acceleration/deceleration time (,) in conformance with mean load allows optimum
setting that conforms to further changes in load.
☆ Use this parameter after actually connecting the motor.
☆ When the inverter is used with a load that fluctuates considerably, it may fail to adjust the acceleration or
deceleration time in time, and therefore may be tripped.
☆ Do not use  = when using a brake module (optional).

☆ Assigning the forced detection command (function number 122, 123) to any logic input terminal, it can be

Manually setting acceleration/deceleration time
Set acceleration time from 0.0 (Hz) operation frequency to maximum frequency  and deceleration time as
the time when operation frequency goes from maximum frequency  to 0.0 (Hz).


The first basic parameter "" (history function) is displayed.

Turn the setting dial to the right to change the parameter to .
Parameter values can be read by pressing the center of the setting
dial.
Press the center of the setting dial to save the changed parameter.
