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-görbe gyorsítsáskor Factory Setting: d 0
Settings d 0 to d 7
1 - 17 S-görbe lassításkor 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).
