Linear acceleration and deceleration is the 
default pattern and is used on most 
applications.
S-pattern 1 is used for applications 
that require quick acceleration and 
deceleration. This setting is also popular for 
applications that require shock absorption at 
the start of acceleration or deceleration.
S-pattern 2 acceleration and deceleration 
decreases the rate of change above the base 
frequency.
