7.11 Acc/Dec Pattern Configuration
The acc/dec gradient level patterns can be configured to enhance and smooth out the
inverter’s acceleration and deceleration curves. A linear pattern features a linear increase or
decrease to the output frequency, at a fixed rate. An S-curve pattern offers a smoother and
more gradual increase or decrease of output frequency, ideal for lift-type loads or elevator
doors, etc. The S-curve gradient level can be adjusted using codes ADV-03
– 06 in the advanced
group.

Acc/Dec Pattern Setting Details
Code Description
ADV-03 Acc S Start
Sets the gradient level as acceleration starts when using an S-curve, acc/dec
pattern. ADV-03 defines the S-curve gradient level as a percentage up to half
of the total acceleration.
If the frequency reference and maximum frequency are set at 60 Hz and
ADV-03 is set to 50%, ADV-03 configures the acceleration up to 30 Hz (half of
60 Hz). The inverter will perform S-curve acceleration in the 0-15 Hz
frequency range (50% of 30 Hz). Linear acceleration will be applied to the
remaining acceleration within the 15
– 30 Hz frequency range.
ADV-04 Acc S End Sets the gradient level as acceleration ends when using an S-curve acc/dec
