+ When automatically setting acceleration/deceleration time, always change the acceleration/deceleration
time so that it conforms to 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).
+ Setting acceleration/deceleration time (CEE,FGE) in conformance with mean load allows optimum
setting that conforms to further changes in load.
+ Use this parameter after actually connecting the motor.
+ 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.
■ Methods of setting automatic acceleration/deceleration
Key operated LED display Operation
Displays the operation frequency.
(When standard monitor display selection H is set to
[Operation frequency])
CWH
The first basic parameter “CWH” (Wizard function) is displayed.
CWK
Press the key to change the parameter to CWK.
Pressing the ENT key allows the reading of parameter setting.
Press the key to change the parameter to or .
⇔CW
Press the ENT key to save the changed parameter. CW and the
parameter are displayed alternately.
5.1.2 Manually setting acceleration/deceleration time
Set acceleration time from 0 (Hz) operation frequency to maximum frequency HJ and deceleration time as
the time when operation frequency goes from maximum frequency HJ to 0 (Hz).
