Acceleration and deceleration curve, also known as "Ramp Frequency Generator (RFG)", is used to smooth the frequency
command. IR610 supports the following acceleration and deceleration curve:
0: linear acceleration / deceleration
The output changes at a constant acceleration or deceleration. Acceleration time refers to the time from when the inverter
accelerates from zero to the reference frequency (selected by P03.15); deceleration time refers to the time required to
decelerate from the reference frequency to zero.
1: S curve method
This acceleration and deceleration curve acceleration "a" changes in a ramp, start and stop relatively flat. Acceleration and
deceleration process as shown below, Tacc and Tdec for the set acceleration and deceleration time.
The acceleration and deceleration curve of the equivalent acceleration and deceleration time:
Acceleration time = Tacc + (Ts1 + Ts2) / 2
Deceleration time = Tdec + (Ts3 + Ts4) / 2

2: S curve method B
The time of this S-curve is defined as in the method A except that in the acceleration / deceleration process, if the target
frequency suddenly approaches or the acceleration / deceleration time changes, the S-curve is re-planned. In addition, when
the target frequency changes, the S Curves avoid "overshoot" as much as possible.
