5.3 Setting acceleration/deceleration time
5.3.1 Automatic acceleration/deceleration
：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 or , depending on the current rating of the inverter.
=
* Automatically adjusts speed during acceleration only. During deceleration, speed is not adjusted
automatically but reduced at the rate set with .
Set (automatic acceleration/deceleration) to or .

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 = when using a brake module (optional).
