Functions
•To select an acceleration or deceleration pattern, use A097 or A098, respectively.
•You can set acceleration and deceleration patterns individually.
•If any item other than "Line" (A097/A098 = 00) is selected for the acceleration/deceleration pattern,
the acceleration/deceleration time is prolonged when this function is used with analog input (A001 =
01).
Pattern Selection
Select an acceleration/deceleration pattern with reference to the following table.

Description
Accelerates/
Decelerates
linearly before
reaching the set
output frequency
value.
Helps prevent the
collapse of cargo
on the elevating
machine or
conveyor.
Helps with tension control and roll break
prevention (for a winding machine, etc.).
Provides shockless
start/stop as with
the S pattern, but
the intermediate
section is linear.
