Chapter 5 Description of Parameter Settings

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/deceleration, and stall prevention

during deceleration.

d 5 Auto acceleration, linear deceleration, and stall

prevention during deceleration

& If the auto accel/decel is selected, the AC drive will accel/ decel in the

fastest and smoothest means possible by automatically adjusting the time

of accel/decel.

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

Settings d 0 to d 7

1 - 17 Deceleration S-Curve 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 accel/decel

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 accel/decel time will be

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

accel/decel time will be determined based on the S-curve selected (d1 to

d7).
