Adjusting Acceleration and Deceleration Time Using an Analog Input
If you set H3-09 (Analog Input Terminal A2 Function Selection) to 5 (acceleration/deceleration time gain),
you can adjust the acceleration/deceleration time using terminal A2's input voltage.
The resulting acceleration time is as follows:
Acceleration time = C1-01 set value x acceleration/deceleration time gain
Fig 6.24 Acceleration/Deceleration Time Gain Using an Analog Input
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.
Four different S-curve characteristic times can be set: At acceleration start, at deceleration start, at acceleration
end and at deceleration end.
Setting Example
The S-curve characteristic when switching operation (forward/reverse) is shown in the following diagram.
Fig 6.25 S-curve Characteristic during Operation Switching
INFO
When S-curve is set, calculate acceleration/deceleration time as follows:
Acceleration/deceleration time gain
(Acceleration/deceleration gain from 1 to 10 V)
= 10 V/Input voltage (V) x 10 (%)
