VFD-S Series

5-10

1 - 15 Auto Acceleration / Deceleration Factory Setting: d 0

Settings d 0 Linear acceleration / deceleration.

d 1 Auto acceleration, linear Deceleration.

d 2 Linear acceleration, auto Deceleration.

d 3 Auto acceleration / deceleration

d 4 Linear acceleration, auto deceleration, and stall prevention

during deceleration.

d 5 Auto acceleration, auto deceleration, and stall prevention

during deceleration



If the auto acceleration/deceleration is selected, the AC drive will

acceleration/deceleration in the fastest and smoothest means possible by

automatically adjusting the time of acceleration/deceleration.

1 - 16 S-Curve in Acceleration Factory Setting: d 0

Settings d 0 to d 7

1 - 17 S-Curve in Deceleration Factory Setting: d 0

Settings d 0 to d 7



These two parameters allow you to configure whether the acceleration and/or

deceleration ramps are linear or S-shaped. The S-curve is enabled when set at d1-d7.

Setting d1 offers the quickest S-curve and d7 offers the longest and smoothest S-curve.

The AC drive will not follow the acceleration/deceleration time in Pr.1-09 to Pr.1-12. To

Disable the S-curve, set Pr.1-16 and Pr.1-17 to d0.



From the diagram shown below, the original setting acceleration/deceleration time will

be for reference when the function of the S-curve is enabled. The actual

acceleration/deceleration time will be determined based on the S-curve selected (d1 to

d7).
