Learning Basic Features
Acc/Dec Pattern Configuration
A Linear Accel and Decel pattern features a linear increase (and decrease) of the output frequency
at a fixed rate. An S-curve pattern provides a smoother and more gradual increase (and/or
decrease) of output frequency. Acc/Dec gradient level patterns can be configured to enhance and
smooth the inverter’s acceleration and de celeration curves. This is ideal for lift-type loads or
elevators. An S-curve can be set with Ad.01 (accel) and Ad.02 (decel) and gradient levels can be
adjusted using Ad.03 ~ Ad.06.

Code and Features Description
Ad.01
Acceleration Pattern
Select 0 (Linear) or 1 (S-Curve) Acceleration Pattern
Ad.02
Deceleration Pattern
Select 0 (Linear) or 1 (S-Curve) Deceleration Pattern
Ad.03
Acc S Start
Ad.03 sets the gradient level at the start of the acceleration curve. The
set percentage applies to 50% below the first half of the total
acceleration curve. When the frequency reference is set at 60 Hz and
Ad.03 is set to 50%, S-Curve acceleration will be applied to 0 – 15 Hz.
(50% below half the reference frequency). Linear acceleration will be
applied to the 15-30 Hz. section.
Ad.04
Acc S End
Ad.04 sets the gradient level at the end of the acceleration curve. The
set percentage applies to the second half of the total acceleration curve
where operating frequency is reaching the reference frequency. When
the reference frequency is 60 Hz. and Ad.04 is set to 50%, S-Curve
acceleration will be applied to 45-60 Hz. (50% above half the reference
frequency). Linear acceleration will be applied to the 30 – 45 Hz. section.
Ad.05
Dec S Start –
Sets the gradient level at the start of S-curve deceleration. S-Curve
deceleration is applied to the portion of the deceleration curve that is
50% above half the reference frequency (60-45 Hz.). Same as S-Curve
End acceleration.
Ad.06
Dec S End
Sets the gradient level at the end of S-curve deceleration. S-Curve
deceleration is applied to the portion of the deceleration curve that is
50% below half the reference frequency (15-0 Hz.). Same as S-Curve
start acceleration.
