The inverter provides 4 sets of acceleration and deceleration time, which are P0-17\P0-18
and the above three groups of acceleration and deceleration time.
The definitions of the four groups of acceleration and deceleration are exactly the same.
Please refer to the descriptions of P0-17 and P0-18. Through the different combinations
of multi-function input terminals, you can switch between 4 groups of
acceleration/deceleration time, see P4-01~P4-05.

When the set frequency is within the skip frequency range, the actual operating
frequency will run at a skip frequency that is closer to the set frequency. By setting the skip
frequency, the inverter can be avoided from the mechanical resonance point of the load.
Two skip frequency points can be set. If both skip frequencies are set to 0, the skip
frequency function is canceled. The principle of the hopping frequency and the hopping
frequency amplitude is shown in Figure 6-14.
