Program two of the parameters H1-xx to “07” and “7A”. The combination of these
two inputs activates the acceleration/deceleration times as shown below. As the
contacts of the terminals open and close, the following acceleration and
deceleration time combinations are possible:
■ Automatically Switching Acceleration/Deceleration Times
The drive can automatically switch between acceleration and deceleration times.
When the output frequency reaches the value set to C1-11, the drive will switch
acceleration and deceleration times as shown in the graph below. Setting C1-11 to
0.0 Hz disables this function.
