4.11 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 ADV-03–06 in the advanced group.

Description
ADV-03 Acc S
Start
Sets the gradient level as acceleration starts when using an S-curve,
Acc/Dec pattern. ADV-03 defines S-curve gradient level as a percentage,
up to half of total acceleration.
If the frequency reference and maximum frequency are set at 60 Hz and
ADV-03 is set to 50%, ADV-03 configures acceleration up to 30 Hz (half
of 60 Hz). The inverter will operate 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 pattern. ADV-03 defines S-curve gradient level as a percentage,
above half of total acceleration.
If the frequency reference and the maximum frequency are set at 60 Hz
and ADV-04 is set to 50%, setting ADV-04 configures acceleration to
increase from 30 Hz (half of 60 Hz) to 60 Hz (end of acceleration). Linear
