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

Slip compensation value adjusted by the following parameters to ensure stable speed under
load fluctuations and heavy load,
C09 Low Slip Gain
C10 Low Slip switching frequency

The set frequency lower than the minimum running frequency, the converter will stop, that
is, when the set frequency is less than the minimum running frequency, are determined that the
set frequency is 0.
Minimum running frequency" and "lower frequency" relationship is as follows.
