5. Basic parameters
Before you operate the inverter, the parameters that you must first program are the basic parameters.
5.1 Setting acceleration/deceleration time
CW ：Automatic acceleration/deceleration
CEE
：Acceleration time 1
FGE
：Deceleration time 1
• 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.
5.1.1 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.
