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 Ad. 03–06 in the Advanced group.

Description
Ad.03 Acc S Start
Sets the gradient level as acceleration starts when using an S-curve,
Acc/Dec pattern. Ad. 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 60Hz and
Ad.03 is set to 50%, Ad. 03 configures acceleration up to 30Hz (half of
60Hz).The inverter will operate S-curve acceleration in the 0-15Hz
frequency range (50% of 30Hz). Linear acceleration will be applied to the
remaining acceleration within the 15–30Hz frequency range.
Ad.04 Acc S End
Sets the gradient level as acceleration ends when using an S-curve
Acc/Dec pattern. Ad. 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 60Hz and
Ad.04 is set to 50%, setting Ad. 04 configures acceleration to increase from
30Hz (half of 60Hz) to 60Hz (end of acceleration). Linear acceleration will
be applied within the 30-45Hz frequency range. The inverter will perform an
S-curve acceleration for the remaining acceleration in the 45–60Hz
frequency range.
Ad.05 Dec S Start
–
Ad.06 Dec S End
Sets the rate of S-curve deceleration. Configuration for codes Ad.05 and
Ad.06 may be performed the same way as configuring codes Ad.03 and
Ad.04.
