1 Indicate that the slope of the output frequency from 0 to the max.
2 Indicate that the slope of the output frequency at constant segment.
3 Indicate that the slope of the output frequency is reduced to 0 from the max.
Such as setting the S curve acceleration and deceleration, acceleration and deceleration time
from 0Hz to the maximum frequency is calculated as follows:
Plus acceleration S characteristic time = F09 * F20
Constant extra acceleration S characteristic time = F09-(F09 * F20 + F09 * F21)
Minus acceleration S characteristic time = F09 * F21
Full acceleration time = F09 Acceleration time
Velocity S addition and subtraction characteristic time = F10 * F22
Constant deceleration S characteristics time = F10-(F10 * F22 + F10 * F23)
And reduction rate of S characteristic time = F10 * F23
All deceleration time = F10 deceleration time
