Its meaning is identical with speed-up/speed-down time 1 (F0-09 and
F0-10). Refer to the descriptions of F0-09 and F0-10 function codes for
details.
It can select speed-up/speed-down time 1 or speed-up/speed-down time 2
through the external digital input terminal DI. Refer to the function
description of “Speed-up/Speed-down.Selection Terminal” of function
codes of Group F2-00 to F2-04 for details.

It can make the inverter run away from the mechanical resonance point by
setting the skip frequency.
The inverter cannot run at the frequency point within the skip frequency
range. If the setup frequency is within the skip frequency range, the actual
running frequency will run at the boundary of the skip frequency, as shown
in Fig.6-13.
One skip frequency point can be set for this inverter. If the skip amplitude is
set to 0, this function has no action.
