Jump frequency is set to prevent the output frequency of inverter from meeting the
mechanical resonant point of load.
In Jump frequency parameters, set the system's mechanical resonant central frequency, at
most three frequency values can be setup, shown in Fig.6-8.

Setting range: 0.1
～
3600s
FWD/REV dead time: the waiting and holding time before the motor changes its rotating
direction after the inverter's output frequency is decreased to zero. It is the time taken by the motor
to change its rotating direction when the inverter receives REV command during its running
process. The time is shown in Fig. 6-9 as T0.
