4.9 Acc/Dec Pattern Configuration
Acc/Dec gradient level patterns can be configured to enhance and smooth the
inverter’s acceleration and deceleration curves. Linear pattern features a linear
increase or decrease to the output frequency, at a fixed rate. For an S-curve pattern a
smoother and more gradual increase or decrease of output frequency, ideal for lift-
type loads or elevator doors, etc. S-curve gradient level can be adjusted using codes
Ad. 03
–06 in the Advanced group.

Description
Ad.03 Acc S
Start
If the acc/dec pattern is set as the S-curve, set the gradient level (slant)
for the acceleration start time. Gradient level is the ratio which gradient
acceleration takes up in the section under 1/2 frequency based on the
1/2 frequency of target frequency.
If the frequency reference and maximum frequency are set at 60 Hz
and Ad.03 is set to 50%, 0
–15 Hz section will conduct curve
acceleration and the 15-30 Hz section will conduct linear acceleration
when the S-curve accelerates up to 30 Hz.
Ad.04 Acc S
End
Set the gradient level for when the operation frequency reaches the
target frequency.
The curve ratio is the ratio that the curve acceleration takes place
within the section above the 1/2 frequency, based on the 1/2 frequency
of the frequency reference.
If the setting is set identical to the Ad.03 Acc S Start example, the 30
–
45 Hz section will conduct linear acceleration. The 45
–60 Hz section
will first conduct curve acceleration then conduct at a constant speed.
Ad.05 Dec S
Start
–
Ad.06 Dec S
Sets the rate of S-curve deceleration. The setup method is the same
as the ratio during acceleration.
