acceleration/deceleration time unit is “0.1s”.
Except for that in torque control (F13.06), all
the acceleration and deceleration time will change.
For example,
the value of F00.14 will
change from 15.00s to 150.0s by default.

The frequency hopping function (FH function for short) can prevent the output
frequency of the inverter from the mechanical resonance frequency point of the mechanical
load. If the inverter is prohibited from running at a constant speed within the frequency
hopping range, hopping will not occur during acceleration. Instead, the inverter will run
smoothly.
