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

5.1 Setting the acceleration and deceleration times

 Deceleration time #1

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 r ange 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 in verter'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
