Figure 3‑61 Jump frequency
In the preceding figure, when the running frequency approaches the jump frequency
during acceleration, the AC drive runs for a period at the current running frequency
and then jumps over the jump frequency. The jump range is twice F8‑11 (jump
frequency amplitude).
When the running frequency approaches the jump frequency during deceleration, the
AC drive runs for a period at the current running frequency and then jumps over the
jump frequency. The jump range is twice F8‑11 (jump frequency amplitude).

You can set the jump frequency to enable the AC drive to
avoid mechanical resonance point of load. This
parameter specifies the first jump frequency. If it is set
to 0, the first frequency jump function is disabled.
