Jump Frequencies – Some motors or machines exhibit resonances at particular

speed(s), which can be destructive for prolonged running at those speeds. The inverter

has up to three

jump frequencies causes the inverter output to skip around the sensitive frequency

Jump freq. (center) 1 to 3

Jump freq. width

(hysteresis) 1 to 3

jump frequencies

as shown in the graph. The hysteresis around the

"A" Function

Up to 3 output frequencies can

be defined for the output to

jump past to avoid motor

resonances (center frequency)

Range is 0.0 to 400.0 Hz

Defines the distance from the

center frequency at which the

jump around occurs

Range is 0.0 to 10.0 Hz
