Acceleration and Deceleration Characteristics

îš„Entering S-curve Characteristics in the Acceleration and Deceleration Time
By performing acceleration and deceleration using an S-curve pattern, you can reduce shock when starting and
stopping the machine.
Using the Inverter, you can set an S-curve characteristic time for each of the following: Acceleration start
time, deceleration start time, acceleration end time, and deceleration end time.
Setting Example
The S-curve characteristic when switching operation (forward/reverse) is shown in the following diagram.
Fig 6.22 S-curve Characteristic during Operation Switching
INFO
Set the S-curve characteristic time to lengthen acceleration/deceleration time as follows:
Acceleration time = Selected acceleration time + (Acceleration start time S-curve characteristic time +
Acceleration end time S-curve characteristic time) / 2
Deceleration time = Selected deceleration time + (Deceleration start time S-curve characteristic time +
Deceleration end time S-curve characteristic time) / 2
