5.2.1 Automatic acceleration/deceleration
This automatically adjusts acceleration and deceleration time in line with load size.
CW =
* Adjusts the acceleration/deceleration time automatically within the range of 1/8 to 8 times as long as the time
set with the CEE or FGE, depending on the current rating of the inverter.
CW =
* Automatically adjusts speed during acceleration only. During deceleration, speed is not adjusted
automatically but reduced at the rate set with FGE.

+ 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 (CEE, FGE).
+ When using a braking resistor or braking unit, do not set the CW=. Or the regenerative braking resistor may be
overloaded.
+ Use this parameter after actually connecting the motor.
+ Setting acceleration/deceleration time (CEE, FGE) in conformance with mean load allows optimum setting that
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.
•Function
1) For acceleration time 1 CEE programs the time that it takes for the inverter output frequency to go from
0Hz to maximum frequency HJ.
2) For deceleration time 1 FGE programs the time that it takes for the inverter output frequency to got from
maximum frequency HJ to 0Hz.
