:
Automatic acceleration/deceleration
Function
This automatically adjusts acceleration and deceleration time in line with load.
Refer to section 5.3.2 for setting acceleration/ deceleration time manually.

* Adjusts the acceleration/deceleration time automatically within the range of 1/8 to 8 times as long as the time
set with the

automatically but reduced at the rate set with

When automatically setting acceleration/deceleration time, always change the acceleration/deceleration time
so that it conforms to the load. For inverters that require a fixed acceleration/deceleration time, use the
manual settings (
,
).
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
