Basic parameters refer to parameters you need to set before the first use after purchase.

5.1.1 Automatic acceleration/deceleration
In this mode, the acceleration and deceleration times are changed automatically
according to the load applied.
The acceleration and deceleration times are adjusted automatically within a range of
1/8 to 8 times longer than the times set with the and the , respectively.
Set the parameter (automatic acceleration/deceleration) at (enabled).

:
Manual acceleration/deceleration
Enabled (automatic setting)
When the automatic acceleration/deceleration is selected (enabled), the acceleration/deceleration times
constantly change according to the load condition. So, use the manual setting(,) for machines
that need to be accelerated and decelerated always at constant rates.
Set manually the acceleration and deceleration times ( ) in the case that braking resistor or
braking unit is applied ( ).
Before setting this parameter, connect the inverter to the motor.
5. Explanation of the basic parameters
Function
1)The acceleration time parameter is to set the time in which the inverter's output
frequency goes up from 0 Hz to the maximum frequency .
2)The deceleration time parameter is to set the time in which the inverter's output
