5.2.1 Automatic acceleration/deceleration

This automatically adjusts acceleration and deceleration time in line with load size.

Title
When automatically setting acceleration/deceleration time, always change the acceleration/deceleration time so
that it conforms with the load.
The acceleration/deceleration time changes constantly with load fluctuations.
For inverters that requires a fixed acceleration/deceleration time, use the manual settings (
When using a braking resistor or braking unit, do not set the
overloaded.
Use this parameter after actually connecting the motor.
Setting acceleration/deceleration time (
conforms to further changes in load.
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.
