1: S curve acceleration/deceleration
The output frequency is decreased or increased according to the S curve, as shown in Fig. 6-44.
Fig.6-44 S curve acceleration/deceleration
The speed setting value is in the S curve status at the beginning of the acceleration and when it reaches
the desired speed, and at the beginning of the deceleration and when it reaches the desired speed. Thus,
the acceleration and deceleration can be smooth and there is less impact. The S curve
acceleration/deceleration mode is applicable to the start and stop of carrier of transportation and
transmission, such as the elevator, conveyor, etc.
0: 0.1s
1: s
2: min
This function is used for defining the time unit for all the acceleration/deceleration operations, except for
the jog operation.
