Acceleration and Deceleration Characteristics
‹
Setting Acceleration and Deceleration Times
Acceleration time indicates the time to increase the output frequency from 0% to 100% of the maximum out-
put frequency (E1-04). Deceleration time indicates the time to decrease the output frequency from 100% to
0% of (E1-04). The factory setting of the acceleration time is C1-01 and the factory setting of the deceleration
time is C1-02.

Switching Acceleration and Deceleration Time Using Multi-Function Input Terminal Com-
mands
Using the SYSDRIVE PV, you can set two acceleration times and two deceleration times. When the multi-
function input terminals (H1-oo) are set to 7 (acceleration/deceleration time selection 1), you can switch the
acceleration/deceleration time even during operation.
The following table shows the acceleration/deceleration time switching combinations.

Description
Set the acceleration time to accelerate from 0 to the maxi-
mum output frequency, in 1-second units.
Set the deceleration time in seconds for the output fre-
quency to fall from 100% to 0%.
Acceleration time when multi-function input "Accelera-
tion/deceleration time selection 1" is ON.
Deceleration time when multi-function input "Accelera-
tion/deceleration time selection 1" is ON.
Set the frequency at which acceleration/deceleration time
switches automatically.
Less than set frequency: Acceleration/deceleration time 2
Set frequency or above: Acceleration/deceleration time 1
Multi-function inputs "Acceleration/deceleration time
selection 1" and "Acceleration/deceleration time selection
2" are given priority.
Set the S-curve characteristic time for each part in sec-
onds.
When you set the S-curve characteristic time, the start time
and end time S-curve characteristic time's acceleration
time is lengthened by 1/2 only.
