The 1st section and the last section in accelerating or decelerating are in smooth transition. The
acceleration/deceleration curve is similar to S curve. When it is in S curve, the final
acceleration/deceleration time= S curve time+ Linear acceleration/deceleration time. See Figure 6-13
for 2 acceleration/deceleration modes.
See Figure 6-6 for 2 acceleration/deceleration modes.

All the unit of acceleration and deceleration time is 0.1s, the function code decimal point of 4
section acceleration and deceleration time（b2.00~b2.07), jog acceleration and deceleration time, 4
section S-curve time（b2.11, b2.15~b2.17) is one.

This function is valid when motor 1 is selected and acceleration/deceleration time switchover is
not performed by means of DI terminal. It is used to select different groups of acceleration/deceleration
time based on the running frequency range rather than DI terminal during the running process of the
AC drive.
During acceleration, if the running frequency is smaller than the value of b2.13, acceleration time
2 is selected. If the running frequency is larger than the value of b2.13, acceleration time 1 is selected.
During deceleration, if the running frequency is larger than the value of b2.14, deceleration time 1
is selected. If the running frequency is smaller than the value of b2.14, deceleration time 2 is selected.
